Give streamers the ability to have multiple audio channels, one for voice, and one for music. This gives them the ability to play music, and the end user the ability to either listen to that music at a level they like, or the ability to mute it altogether. Not everyone has the same taste in music, and this would also allow streamers to play their music and not have to worry about their voices being muted if they play music that's copywrited, as the music channel can just be muted if that's the case.
