2009 studio album from the Grammy-winning singer/songwriter.

Since the release of his hit album, Room For Squares, in 2001, Mayer has progressed from a sensitive acoustic-based performer into a full-fledged paparazzi-baiting superstar with acclaimed musical detours into Jazz, Blues and Folk.

Battle Studies is yet another milestone for Mayer, containing some of his best work to date. Features the single 'Who Says'.
