'Rock Band' pumps up music sales

— -- The success of the video game Rock Band is drumming up revenue for the music industry.

Virtual rockers downloaded roughly 2.5 million songs in the eight weeks since the game launched on the Microsoft Xbox 360 and Sony PlayStation 3 systems.

Rock Band, developed by Harmonix, which also created Guitar Hero, comes with 58 playable songs including the Rolling Stones' Gimme Shelter and Metallica's Enter Sandman. But many more tunes can be downloaded over the PlayStation Network and Xbox Live for prices varying from 99 cents to $2.99.

"Hopefully it helps evolve music to not just a linear art form but a more interactive art form," says Van Toffler of MTV Networks. MTV Games publishes Rock Band, along with Electronic Arts. "You look at a lot of 20-year-olds who are reticent to plop down $20 for a CD, yet they don't mind paying $25 for a DVD or $50 for a video game. … We're seeing the audience really embrace hearing new music for the first time or engaging with classic rock songs in a new way."

New songs are available weekly for Rock Band. And musicians and bands are lobbying to get their songs in the game. "As opposed to us being the aggressor, a lot of the classic bands and the biggest bands in modern music history are approaching us now to be in the game," Toffler says.

More than 1 million copies of the game have been sold, according to the NPD Group.

The special edition of the game ($170 for PS3 and Xbox 360, $160 for PS2, available since Dec.18) comes with microphone and guitar and drum peripherals; the standalone game is $60 (PS2 version, $50).
