No bands in Get Famous?

I feels like bands should be their own game pack as i would expect them to add new instruments and if they are anything like all the past instruments in ts4 they will add 10+ genres for them to play including the ones you can license this also isn't including the songs and genres they'd add for the bands themselves. This would lead to a lot of audio assets and though you can't physically see them they are assets none the less. This is one of the reasons why when they started making the singing skill for karaoke it ended up going from a 5lv skill to a full 10.

I also don't want a repeat of bands from ts3 as I could never get them any gigs or one or more of the other bandmates never showed. This is why I think they would have to create a whole nother system and potentially a new venue type similar to to the ones from showtime.
