It would definately have to be the music from "Sweeney Todd: The Demon Barber of Fleet Street". I also love the music to "Edward Scissorhands" and "The Nightmare Before Christmas"; pretty much anything by Danny Elfman (he composes like EVERY Tim Burton movie soundtrack).
Oooooooooooh! Hairspray... Wait, no, Bridge to Terrabithia.... No, Twilight! Wait, wait! New Moon! No.... Eclipse!!! IDK, those are like, my most fave, not in order, but... I LIVE for movie soundtracks, haha. :)
There are lots of them...I like soundtracks from Pearl Harbor, Armageddon, Once Upon A Time In America(probably the best soundtracks ever), Brave Heart, Gladiator, Pirates Of The Caribbean and many many others.
