The Shins are nice, yes, but Frou Frou on that is WAY better.
ANYWAY, I really like movies scores (the orchestral or whatever) music as a genre a LOT. My favorite composer is Tomas Newman (Angels in America, Erin Brachovich, Finding Nemo, etc). He has his own amazingly unique style. I also really love Harry Gregson-Williams (Narnia movies) and Hishashi Joe (the Miyazaki Ghibli movies). And the soundtracks to the first two NeverEnding Story movies and Labyrinth and Legend (both versions) and . . . on and on. :P
