Linkin Park - "New Divide" (Instrumental version)
I haven't watched any of the "Transformers" movies, one of which uses this song; instead, I happened upon it while listening to songs on MySpace. I like its simple, sullen, gloomy, and driven feeling.
I listened to the start of the version that has vocals, but I felt the singing was a distraction, so I prefer this instrumental version:
