These are all wonderful ideas. I'd like to see the singing career pulled out a little more as well like a solo singer or singer in a band. Music options for all of it should be popular and or classical music styles, it could fit in with likes/dislikes.
Career paths could include Singer or Vocalist: where your sim could be Soloist or Singer in a group or band. A choral option would be cool too. The sims could practice/perform or play in impromptu combinations like duets, trios, bands, orchestras, and choirs, instrumental or vocal only or both together. Opportunity for some lovely vocal harmonizing as well (I love, love the country duet on the karaoke machine).
Musical styles must include Rock n Roll band, Blues, classical ensemble variations, Punk Rock band, Metal band, Jazz, Hip Hop, Pop with genre appropriate stage wardrobes and makeup to match.
I'd also prefer that the music/bands pack not be crammed into a small stuff pack but made into a bigger game pack at the very least.
