Allow streamers to create listening parties on Spotify that viewers can sync to.
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.
-Integrated song request system
-Spotify pays twitch $$$ for this partnership
-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
