Allow Musicians to play their own Music that they've composed themselves and have uploaded on Music streaming services or have a copy of the music on their devices that they play the music with.
For example, I've composed 2 albums that are available on Spotify and other Music streaming services, and I'm still getting my audio muted because twitch doesn't allow any spotify tracks to be played during a stream.

So, I'm hoping twitch can allow Streamers to play their own music, by adding a portal where they can connect their Music copyrights (email address could be enough), and then play it once the streamer is approved via this portal.
