I'll have to think about this for this time around too. I never had music last time, and I dunno, even though I was at a birth centre, it sort of felt all clinical, and I felt a bit exposed (could of been cos it was in a really lit room and I never had a cave or anything to go into!!) I need a cave.. and if I can't get it.. chilling out to music seems good... but my list will probably be a LOT different than yours.. LOL
