I liked a lot of what was played on the shows. It was a nice mix between contemporary (a lot of alternative rock at the Bronze and contemporary ballads that were regulars on every WB show), oldies (much of it due to Caritas, Lorne and Angel), various genres based upon a character or setting (Joss is a known fan of country music and it rears itself as Xander and Fred's music of choice), instrumental scores, classical, etc... I have practically every song heard on the shows/movie (even songs only referenced) on my computer (I've been a Whedonite for quite a while).
