Acti-Blizz Day - Guitar Hero boosts track sales by 200-300%

Speaking during Activision Blizzard’s Analyst Day last night, Universal Music Group president Zach Horowitz claimed that inclusion in Guitar Hero would boost a track's sales by as much as 300 percent.

Horowitz added for emphasis that "My Name is Jonas," a Weezer track included in Guitar Hero III, saw a real-world sales increase of 1,000% in the weeks following the game's release.
