5. The Departed.

I agree more Radiohead. Specifically, 'Just' would be an awesome DLC song.

All of the annoying beggers in Assasin's Creed.

Mass Effect had an awesome and unique soundtrack that fit the visuals and mood of the game perfectly. 
Super Mario Galaxy was also pretty great, the way the orchestra would build in the main world as you progressed in the game.
