Really Really want a choir in the Sims

I miss the idea bands a lot (even though I can't remember them ever working correctly in Sims 3), along with the ability to jam with other sims, the upright bass and the drumset - more instruments I say! An active career system for musicians is something I'm quite bummed out we didn't get in Get Famous. And a choir or a school orchestra would be a cute after-school activity. Maybe we could get a jazz-themed pack with a 1920s aesthetic at some point.
