More instruments in base game & more instrument interactions

@MJTiny   Hello!  Yes, please!  This has come up fairly often in requests over the years and I've added my "me too" to all that I've seen.  It would be so great to have more instruments and to have some ensembles in which sims can play together; orchestra, chamber music, rock bands (with singers too), etc.   I'd like to have some of this added to Base Game of course but I would also pay for a full Music pack that includes expanded Musician careers, concert venues and recording studios.  Fingers crossed!  Thanks for sharing!
