John Mayer's best selling album is his 2001 release Room For Squares selling over 4 million copies to date. Heavier Things (2003) has sold right under 3 million copies. Continuum (2006) has sold over 3 million copies. Battle Studies (2009) has sold about 880,000 copies. I'm not sure how many copies Inside Wants Out has sold. It was his first album/self release in 1999 then was re-released by Columbia Records in 2002.
