CAROUSEL hs a beautiful score but requires singers with some training.
It also requires a level of acting where the performers can underscore the subtext.
Few community production can do both and some can't do either well.
It also is a fantasy and that is hard to play, and harder for modern audiences to buy into.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
