I just saw this now; but I make a post talking about making a full music related game back that also allowing singers to join bands. Maybe if we get more people interested, we can make it happen. Apparent people made farming a possible future pack as they had polls on twitter about it, so why not also make music pack as reality some day?
I say it should be separate from Uni as it would allow it to be the main focus and more fleshed out. Plus besides some art courses, I don't see Uni really adding a lot to music.
