I like Music, it seems a bit quieter than the others, pretty landscaping, nice fountain. The buses were great. The only long wait we had was at one park closing, because we left with the herd. But if you take your time getting out of the park it gives the bus link plenty of time to thin out (this is true for any resort bus probably).
I have stayed at all the values and Music and Pop are my favorites. I much prefer Music over Movies, the rooms are updated at Music, and until Movies room get a refurb I won't stay there. Here are some exterior shots I took at Music last October:
