While Activision has already made Guitar Hero: Greatest Hits public knowledge, we didn't know what the publisher considers a "greatest hit." Turns out its four dozen tracks from Guitar Hero I, II and III.

That includes, but is not limited to, (deep breath) "Them Bones" by Alice in Chains, "Killer Queen" by Queen, "Nothin' But A Good Time" by Poison, "Killing in the Name" by Rage Against The Machine, "I Wanna Rock" by Twisted Sister, and, of course, "Through the Fire and Flames" by Dragonforce. All tracks in Greatest Hits, according to a new IGN interview are master tracks.

The collection pulls from Guitar Hero, Guitar Hero II, Guitar Hero Encore: Rocks the 80s and Guitar Hero III: Legends of Rock, adding full band play to those already familiar songs.

Guitar Hero: Greatest Hits is planned for a release this June on the Xbox 360, Wii, PS3 and PS2.
