Im a huge fan of, well, ambient/background tracks. Its one thing to like a band, but I always found movie and game soundtracks to be absolutly wonderful. You remember those times when something really intense or moving happened, and the memories adds to the appeal of the music.
I cant think of any recent movie scores I liked aside from inception, so Ill list my top 3 scores
1. Braid
2. World of Goo
3. Mirror's Edge
A lot of horror games have nice scores too (although I personally didnt like dead space's). The main menu track for Condemned is by far one of my favorite.
