Prior to the album's release, three songs were leaked onto the Internet: second single "
Same Girl", which features
Usher; "Rise Up", a song which only appeared on some releases, a tribute to the victims of the
Virginia Tech massacre in April 2007; also making an early appearance was a song titled "Blow It Up", at first supposed to be featured on the album but absent from the final track listing, mainly due to the inappropriate mood it would have created because of the presence of the Virginia Tech shooting tribute song "Rise Up". "
Rock Star", which features
Ludacris and
Kid Rock, was released as the album's third single on September 4. A video for the song "
Real Talk" was also made directly on
YouTube. On May 25, 2007, four days before the album's release, the explicit version of the album became available for purchase on
iTunes. The edited version became available on May 29, 2007, with a bonus track version available a day later. ==Critical reception==
