You can now hear the first single from Fall Out Boy's upcoming fourth album, Infinity on High. It's... interesting to say the least. A little taken from Panic! at the Disco's book, mixed with the indefinite signs of a dire attempt to escape the confines of pop-punk and emo, only to find themselves back in those cages with those whiny vocals and single-hook choruses. The single, "This Ain't a Scene, It's an Arms Race," is scheduled to be released by the end of the year, and you can listen to it here.
