I really like this idea; I think additional instruments and additional musical features would add a little more colorfulness to the game as a whole. I was impressed with the inclusion of the Music Mixing Station from Get Famous, but I'd like to see some actual additional instruments.
Another feature I'd love to see in something like this would be having Sims able to play songs together, rather than individual tracks; I recall Sims 2 doing that a ways back with drums, guitar, base, and piano; it'd be a nice throwback, and it'd also encourage musically-inclined Sims to hang out together; imagine how that would work with clubs that revolve around music?
Just a little food for thought since the topic was brought up.
