Just saying spotify for this example, but it could be any music streaming platform.

Twitch team would have to work with spotify to accomplish this.

-Streamer can control what everyone hears. (Except volume, and maybe some restrictions on how much they can skip so it's not jarring on the viewers)
-Viewers can thumbs up or down songs, if too many thumbs downs occur in a small amount of time, in contrast to thumbs ups, the song is skipped, or a skip request is sent to streamer. Feature can be disabled to prevent abuse.
-Song request queue. Viewers can request songs, and vote on other songs.

How it works is you join a stream, then the streamer has either a code to type into spotify, or qr code, or even a permanant room on spotify that people can just search for the name, maybe even a button that just opens spotify for you right to the listening party.

Pros:
-Avoid DMCA
-Integrated song request system
-Spotify pays twitch $$$ for this partnership

Cons
-Probably a lot of dev work from the spotify end
-Viewers that join listening parties that don't have premium would be interrupted by ads
-Viewers that don't want to join listening parties won't hear any music

I see a number of streamers mentioning about a possible feature to 'share' banned users with the other streamers.
When a group of streamers agreed on sharing the ban list, it means that banning/chat-restricting a user on a streamer's channel will automatically ban/chat-restrict the user on other steamers' channels.

This feature will be helpful because, as a mod, I see multiple times that banned/chat-restricted user usually goes to another streamer (especially the one who's collaborating with the steamer where the ban was made) and start trolling/spamming in their channel. This feature can help streamers to prevent from happening such things beforehand.

Now that subathons and other long streams are trending on Twitch there's a need for feature to notify your followers that you're live during the stream!

Issue currently is that you need to stop your stream and restart it so the followers get notified that your stream is live! For example for subathon this is a big issue because you'll lose viewers when doing this.

Now my suggestion is to give streamer and their trusted mod(s) a chance to announce that the stream is live without stopping the stream! It could be available once in ~24 hours so it doesn't feel like spam.

Example. Streamer X is having subathon which includes sleeping on stream. Now every morning viewer count goes down a lot. Now when they wake up and/or start new day of content they could press a button which would notify all their followers that now the content starts again.

Hello Twitch,

You tell us that using third-party sites to watch multiple Twitch streams at the same time is detrimental to our chat experience. I totally understand the sense of loyalty and fidelity we must have towards you, but to be honest, I expected better.

Watching multiple streams at the same time would allow us to stay in touch with multiple communities at the same time and not miss any highlights. So why not? Creating the Squad Stream system was a good initiative to follow several streamers on a common game. But if you are so keen to keep us on your platform, I have a proposal for you.

In addition to the Squad Stream, why not launch the Multiview system? This would be an official feature that would allow viewers to follow any streams at the same time on your official site or platform, without using a "third party" site.

I hope this feedback will help you improve our viewer experience. Thank you for your attention.

I would love to see a feature or extension that allows for you to sync your Spotify and Amazon Music.

Currently the Amazon Music extension is not 100% you need to login and listen and the problem is you have to listen on another device meaning if you are listening on your PC your viewers will hear the music not only that they need to opt into the extension to hear it.

If there was a better feature for example something under the streamer or to the left of the video quality options much like the soundtrack one we could then give the option to the viewer to low or mute the background music. Currently the viewer needs to have amazon prime to listen along where this option should not be a thing.

Most users have Spotify and if they are listening along and do not link their accounts to Spotify or Amazon music then while listening they could hear a small ad potentially.

Overall I miss my normal music and I am not a fan of the amount of DMCA music.

I hope Twitch can come up with something.

Implement streaming with multiple, separate audio tracks.

This is all going to sound more complicated and advanced than it really is, so bear with me as I explain it.

Summary:
Viewers would have a single volume slider in the same way as it has always been implemented. It functions as a 'master volume'.
When clicked on a button, an 'audio control panel' would open.
This panel would show multiple volume sliders. One for each audio source or 'track' that the viewer is hearing, and that the streamer is uploading.
One for music, one for streamers' voice/microphone, one for game audio, one for voicechat, etc.

Background:
'Tracks' in this context means the datastream inside the complete file(container) as it is being sent to Twitch.
A container file (mp4, mkv, mov, etc) contains at least one video track and one audio track, but it can contain many more. Think of it as a zipfile.
For example, when you download legitimate films, some videos(which are container files) have a video, audio and subtitle text file as a datastream inside the container. That is why you would see subtitles automatically play in those videos.

The technology is already possible and partially implemented by way of the 'VOD track' option in Twitch and capture software. (You select which audio is put into a second audio track, and only that track is used by Twitch servers to make your VOD, as opposed to your livestream.)

This feature gives several benefits for all parties involved, that offset the relatively marginal increase in throughput data for Twitch. I say marginal, because audio data is much smaller than video data.

Example usecases:
A. A viewer plays a recently released, popular game. They frequently watch a specific streamer that is streaming the same game.
The streamer gives commentary on the game, similar to a podcast.
The viewer does not wish to spoiler themselves on the game, but still wishes to hear their thoughts and opinions on the game.
They can mute game audio, but keep hearing the streamer, whilst the viewer keeps playing the game simultaneously.

B. A streamer is not as tech savvy and is having audio balancing issues.
Viewers are having a lot of trouble hearing the streamer clearly , since the game audio or music drowns out their voice. Or the volume on alerts is shockingly loud.
Viewers can raise the volume of the streamer's voice, and/or lower the volume of the game/music/alerts.

C. A viewer wants to see gameplay of a specific game, possibly a popular newly released game.
The viewer is not interested in the commentary of the streamer, and they find it hard to search for a streamer to their liking.
The viewer mutes the streamers voice, and keeps the game audio on.

D. A streamer is playing a game and has music on.
A viewer enjoys the streamer and their gameplay, but not the music.
The viewer can mute the music but keep the rest intact.

The rundown:
- Streamers get more control over how their audio comes into the stream for their viewers
In a general sense, being able to give more customizable audio experience to viewers minimizes audio issues and annoyances and improves service and community growth
- Removing and managing problematic copyrighted audio becomes much easier
Especially when properly set up on separate track in streaming/capture software, assuming fair usage, emphasis can lie on the specific track(s) that have issues.
- Removing copyrighted audio does not compromise the other audio tracks E.g. mic/self-voice, game audio, voicechat will not have to be muted or altered and it becomes much more straight forward to mute portions of the selected tracks, and can even pave the way to be able to edit in replacement audio.
This applies to both livestream and VODs.
- Viewers get more control over how their audio is managed
Viewers can customize their own experience and streamers become less dependent on the broad availability of different viewer audio setups.
If viewers can get more control over the audio, there are less frustrations for all parties involved.
If a game is too loud, viewers no longer have to complain to the streamer in most cases. Streamers would currently have to pause what they are doing and this stops the flow of entertainment. With this suggested development, these moments become much rarer as viewers can mitigate the issue themselves.
- Viewers can selectively turn off(zero volume) an audio track that the streamer is uploading
For example, to turn off the music the streamer is putting out, or selectively turning on or off microphone, game audio and voice chat audio when watching a multi-stream.
- Opens up a possibility for more behind-the-scenes data/telemetry
This gives streamers more insight and feedback on how viewers experience the stream's audio setup by seeing when and what tracks viewers control/mute.
- Paves the way for game developers to give the option to output multiple audio tracks as well
To further control audio levels, and fight problematic copyrighted music.

I would like to propose that there be an alternative to affiliate we could subscribe to as a content maker. I draw on what turbo and prime's features are, while wishing for features like channel points, reruns, longer expiration queue, and the option to not show ads or show them less - I think this would be worth a monthly Service to sub to when your channel is education or open source making focused. I would subscribe to it in order to take off ads or gain features that are currently unlocked at affiliate only. Just because, with education we are not there primarily for monetizing but would like to be a fully featured channel for our students. Since turbo exists and we don't have to watch pre-roll anymore, I am just thinking of a turbo equivalent for content making and broadcast. Maybe even make it an option that turbo includes if you have hit certain milestones like broadcasts and followers.

Allow creators to restrict viewing of their streams to logged in users only. As an option, this would help address hate raiders who get banned and continue to watch in incognito. Effectively preventing banned users from seeing the stream.

And, at the same time would give creators a simple tool to better control how their content is viewed. For example, if they were creating Mature content and wanted to add their own limitation on consumption.

Provide similar messaging to what is available on logged out Subscriber Streams which say "USER is streaming for 'registered users', Sign up now to join in: Watch the stream and participate in chat." Then a button to create an account.

In the secret stream only certain people can watch it, similar to what you do with sub only, but in this case you can choose several options. Example:

Time limited link, where if you click that link in less than x time after the posting you can watch,
Invite, personal unique invite link,
Multi use Invite link.

And most importantly:
Game Partners.
Interested gaming companies can use some method (apk maybe?) to do ingame verification, and allow people that pass that verification to access the stream, the use for this one is immense since now, for example, for someone that has a clan that is going to war with another clan, they can't stream due to possible spies but now you can if you setup your stream to only be able to be seen from people that are your allies it is now a more "secure" stream, that is only one of the possibilities.

And now you throw them on the front page for a month, if the Secret Stream meets some criteria, (using ingame verification, and can be joined by large number of people) and it will now allow many people that not only would not normally stream in those circumstances, but also people that dont watch streams, since this method can be easily used to coordinate large numbers of people, and give them a visual aid, unlike discord that would only have voice and ten people maximum streams.

Thanks for reading it all.
If twitch doesn't want to do it I might. xD
