If you could make a pack what would it be?

I'd want like a concert pack that comes with like an actual concert venue and then more branches for entertainment like actually make a band in the sims and manage it almost like a restaurant or get to work somehow or you can go solo and manage yourself set your own dates and what not and it come with clothes from like 70s/80s acts and what not. I think that would be cool. At least in my head it sounds awesome!
