My all time favorite soundtrack is probably Ennio Morricone's "The Mission". Such brilliant work! Perfect for the film, but more importantly it stands by itself as lyrical, moving music. Paul Wylie and Karen Kwan used it in two of their finest competitive programs.
Other great soundtracks:
"Rudy"
"Forrest Gump" (themes, not the one with all the 60s songs)
"West Side Story"
"The Time Machine" (the majority are skips...but there are some
that are fast and powerful)
"Requiem for a Dream"
"Legends of the Fall"
"Titanic" (I'm sorry, so cheesy I know, but I still find much of
of that soundtrack and its sequel so moving)
I'll also agree that "Henry V" and "The Hours" have some wonderful moments as well. And I almost always love anything that Andrew Lloyd Webber does.
