The Rock Band 2 soundtrack will feature over 100 songs with over 80 songs on disc plus an additional 20 bonus tracks which will be made available for free download this fall.

Comprised entirely of master recordings from some of rock's most prolific and untouchable artists, including AC/DC, Guns N' Roses, Bob Dylan, Metallica, Pearl Jam and more, Rock Band 2 will deliver the most impressive and largest music catalogue of any music-based videogame ever.
