On May 23, 2007, Activision announced 11 songs that will appear in the game. IGN revealed two more tracks on May 31. A trailer for the game revealed two more tracks on July 9. Users from the ScoreHero forum reported 4 additional songs on July 25, 2007. The list includes both cover songs (indicated by the phrase "as made famous by") and master tracks, featuring performances by the song's original artist. The Living Colour track, "Cult of Personality" was rerecorded (with a new guitar solo) by the band after the master track could not be located. According to IGN.com, this new guitar solo makes the song on expert "just plain ridiculous." On August 16, Gamespot announced that the Poison track Talk Dirty to Me is a remastered version of the original song,  but later that day an official press release noted that it is a "as made famous by" cover version. Several tracks by European artists were announced by Activision on August 22, 2007, and one more track was revealed by Activision on August 23, 2007.
Lead developer Alan Flores states in a GameSpot interview that there will be "over 70 songs", (over half of them master recordings) on the final soundtrack for the game.
