Relapse is the sixth studio album by the American rapper Eminem. It was released on May 15, 2009, through Shady Records, Goliath Artists, Aftermath Entertainment, WEB Entertainment, and Interscope Records. It was Eminem's first studio album after a hiatus following Encore (2004), due to writer's block and an addiction to prescription sleeping medication. Eminem's mentor Dr. Dre produced every track except for "Beautiful", which Eminem produced himself. Guest appearances include Dr. Dre and 50 Cent; a reissue, released on December 21, adds Drake, Kanye West, and Lil Wayne.
