Guitar Hero hits 15 million song downloads

In a conference call yesterday (start at the 29-minute mark), Activision Publishing CEO Mike Griffith confirmed that the Guitar Hero franchise has passed the 15 million mark in individual song downloads. Last week, Harmonix owner Viacom revealed that Rock Band had surpassed the 10 million mark.
