It has been rumored that Guitar Hero III would come out with a classic rock pack. After checking Xbox Live this morning, it appears that there is now a "Classic Rock" Pack available for 500 Microsoft points, or $6.25 for those keeping track at home. The songs that are listed in this pack are all really good songs and should provide a lot of great game play. These songs are: Foreigner's "Juke Box Hero," Journey's "Any Way You Want It" and Boston's "Peace of Mind".
As of right now, we can only confirm these songs for Xbox 360, it maybe that the Playstation version is already live on PSN, but we can't confirm.
