With more than 800 songs already available in the Rock Band Music Store, Harmonix and MTV Games foresee that number reaching 1000 by the time 2010 rolls in.
Speaking at Gamescom 2009 today, Harmonix CEO Alex Rigopulos flaunted his franchise's massive library of music, citing it as just one of the reasons for Rock Band's domination over the competition, along with weekly downloadable content and artist offerings, innovation, and superior gameplay. Rigopulos also revealed that tracks from Queen, Nirvana, Tom Petty, Elton John, Iggy Pop, The White Stripes, Pantera, Talking Heads, Korn, The Raconteurs, and more would soon be bringing said library into the quadruple digits.
The Rock Band catalog passed the 500 song mark back in December of 2008, meaning that if Harmonix's expectations are fulfilled, they will have doubled the amount of tracks available over the course of one year. Maybe that 5000 isn't too far off after all?
