That's eminently clear on Infinity on High, their first album since 2005's From Under the Cork Tree made them heroes of the hoodie set. Despite even thicker coats of studio gloss (a move that gives several tunes a generic edge), High contains catchier hooks, bigger choruses, and more vocal histrionics than a MySpace flame war. It's also more diverse (the pensive piano ballad "Golden" contains a brief spoken-word intro by Jay-Z) and shockingly danceable, with hand claps and disco-flecked backbeats. High's best track is the zing-laden "Thnks Fr Th Mmrs," whose Spanish guitars, scissor-kicking harmonies, cinematic strings, and minor chords crash together messily to form an arena-ready masterpiece.
