Activision today announced the launch week downloadable content for Guitar Hero World Tour (PS2, PS3, X360, Wii), which will be in stores October 26. Immediately available upon release will be Metallica's Death Magnetic album and the Classic Rock Track Pack, which will include "Rock and Roll Band" by Boston, "Hot Blooded" by Foreigner and "Jessie's Girl" by Rick Springfield.

October 30 will see the release of an R.E.M. Track Pack. It will include "Horse to Water," "Man-Sized Wreath" and "Supernatural Superserious" from the band's new album Accelerate. The R.E.M. pack will be an Xbox Live Marketplace exclusive for two weeks, before making its way to the PlayStation Store like the other DLC.

Also available during launch will be "No Rain", the 1992 hit from Blind Melon, and a free download pack that allows gamers to play Ted Nugent and Zakk Wylde's Guitar Duels outside of Career mode.

Outside of the album-only Death Magnetic DLC, tracks in the song packs can be purchased individually or in bundle form. The announcement made no mention of a Wii release for the songs, though the Wii edition of Guitar Hero World Tour has been confirmed to support DLC.
