A way to implement music into twitch is to only play music which has ads in it. Don't allow ad free music without the artist's consent. An example of this is spotify without premium. If a broadcaster streams music let him use non premium and that way spotify is content because their ads are reaching thousands.Spotify pays the artist, they are content. The broadcaster is content with streaming music. The viewers get music and are content. All around problem solved. Maybe this lays the foundation for dmca free. Also I never condone ads but even so,nothing is free.
