With Rock Band lagging a month behind Activision's Guitar Hero 3, Harmonix has released its set list in order to pump up the hype and possibly stir some sales from its main competitors.

The game will ship with 58 songs on the disc, 45 of which will be licensed, and the remaining 13 will be unlockable. Each of these songs can be played with up to four players, playing guitar, bass, drum, and microphone. Four player co-op, both online and off, is Rock Band's biggest perk in its uphill battle against one of gamings hottest series, Guitar Hero.

To fully utilize this, however, you must purchase a bundle for USD 169 (including one guitar, drum kit, and microphone), or strap on your Guitar Hero guitar and go online with buddies.

Guitar Hero launches with more songs than Rock Band, but the set list in Rock Band is more than enough to stand on its own, especially when you consider the fact that downloadable content will be offered on a weekly basis, with several packages already in the talks.

Such packages include a full album from The Who, a hot Metallica track, and several songs from The Greatful Dead.
