The full Rock Band 3 setlist features 83 songs, including a mix of tracks which make use of the new keyboard peripheral and three-part vocal harmonies. Eurogamer's Johnny Minkley noted the contrast between it and the heavier style of Guitar Hero: Warriors of Rock's setlist. Rock Band 3's setlist was well-received by video game critics. During a video interview at the 2010 Gamescom convention, most of the setlist was inadvertently leaked because someone was scrolling through the setlist in the background. The next month, Harmonix used Facebook and Twitter to provide clues about additional songs for both Rock Band 3 and Dance Central, which they then confirmed to be six Rock Band tracks and three Dance Central tracks. When Rock Band 3 was first detailed on June 11, 2010, Harmonix announced 22 of the game's songs. Existing game content, including prior downloadable content and songs from the Rock Band Network, carries forward into Rock Band 3, with the full Rock Band library consisting of over 2,000 songs by the time the game was released. Many were included to emphasize the keyboard instrument. All of the songs included in Rock Band 3 were recorded either from master copies or live performances.
