Activision, meanwhile, said it has sold more than 5 million new songs via download for Guitar Hero III: Legends of Rock since it began adding downloadable content in early November.
By comparison, it took wireless operator Sprint four months to sell 1 million songs on its over-the-air full-song download service. While new digital music services competing with iTunes and free peer-to-peer services have struggled to convince music fans to pay $1 for a single, downloadable tracks for games like Rock Band and Guitar Hero are flying off the digital shelves.
"With such a low installation base, we didn't think that there'd be 2 million songs sold in eight weeks," MTVN Music Group/Logo/Films division President Van Toffler said. "We live in a rough time around music where our audience struggles to pay $20 for a CD but don't hesitate to pay $50 for a game. The notion to pay 99 cents or $1.99 to have a song and repeatedly play with it apparently isn't a big hurdle."
The original Rock Band and Guitar Hero games shipped with more than 50 licensed songs each, a mix of master recordings and covers. Since then, Rock Band has made new music available every week as either singles or in three-pack bundles that can be added as new playable levels for between 99 cents and $5.50. Guitar Hero III did the same, focusing on three-song bundles of new music and music featured in previous versions of the game.
Although MTV is not providing specific numbers, it did say that the majority of the downloaded songs were purchased by as opposed to PlayStation 3 users. According to the NPD Group, "Rock Band" sold 775,000 copies for the Xbox 360 through the end of 2007, compared with 250,000 on the PS3.
The game's impact on song sales for participating artists, however, remains unclear. While not providing exact sales figures, MTV did say that the Metallica three-pack of "Ride the Lightning," "Blackened," and "And Justice for All" is the best-selling Rock Band download.
According to Nielsen SoundScan data, those same songs saw digital download sales spikes of 31 percent, 39 percent, and 48 percent, respectively, for the month after they were featured as a Rock Band download, over the previous month.
But those increased sales numbered only in the hundreds, while the Rock Band downloads numbered in the hundreds of thousands. Still, label executives are thrilled with the results.
MTVN already has plans to expand its outreach to artists, creating additional game expansions--as both physical products and downloadable content--around specific music genres and even artists.
"We are talking to tons of bands, from indie to the most established...to release not necessarily their entire catalog, but maybe some of their classic albums and do special packages around that," Toffler said.
What's more, there's no reason for Guitar Hero and Rock Band to be the only video games that sell music. It's only a matter of time before other games begin offering new downloadable soundtracks as well.
Titles like the Madden football series, the Tony Hawk skateboarding franchise, and the venerable Grand Theft Auto games are well known for their extensive soundtracks. Offering gamers the ability to replace their soundtracks every few months after the initial release is not only technically possible with today's new-generation consoles, but also on the horizon.
"That's certainly something we're interested in," Electronic Arts worldwide head of music Steve Schnur said earlier this month at the Consumer Electronics Show.
