Fall Out Boy's original "Arms Race" is a little annoying, but at least it rocks. Unfortunately, Kanye's rather dark remix of the tune sucks out all of its energy and most of its appeal, putting a sleepy minimalist heat and soulful "ooh"s under the hand's vocals. There's also a silly B-game rap in which Kanye makes fun of FOB's tight pants and says he can't figure out what the song is about. At the end of the day: mildly humorous, but barely worth a mouseclick.

“Time to Pretend”

Listening to MGMT’s breakthrough song, one might interpret it as being about the excesses of rock stardom, but it’s actually about the duo’s pet praying mantis. Ben Goldwasser and Andrew VanWyngarden told Rolling Stone they got the idea from the insect's jerky movements. The mantis died, but the two bandmates kept the egg sack and allowed the hundreds of eggs to hatch. “We tried to name them all, but they died after a day,” said Goldwasser, with VanWyngarden chiming in, “But the praying mantis dance inspired us.”
