The Grateful Dead are back for another round of DLC next week, when the second Grateful Dead pack hits Rock Band.

Like the first pack, this one will contain 6 tracks from the band and can be purchased for $9.99 (800 MS points). 

The tracks are the same ones that were revealed in IGN's preview of the pack.  The full list is after the break.

The full tracklisting for the upcoming Guitar Hero: Metallica game has been revealed!  Featuring 28 tracks from the titular band and 21 more from other artists the band has chosen, you can find a little bit of everything in here - from Queen to Lynyrd Skynyrd to Judas Priest to Slayer.

Additionally, if you've downloaded the full Death Magnetic album for Guitar Hero 3 or Guitar Hero World Tour on the Xbox 360 or PS3, you'll be able to play all of the tracks from the album in the game.  If you get the PS2 or Wii version of the game, it will include 3 bonus tracks from the album.

The game will be released for Xbox 360 and Playstation 3 on March 29, and later in spring on the PS2 and Wii.

A few more tidbits about upcoming Rock Band DLC have leaked out onto the web today.  Via ScoreHero, a three-pack of Thin Lizzy songs will be coming to Rock Band, to coincide with the release of a new live album coming out.  The exact songs are unknown at this time.

Additionally, IGN has posted a review of the second Grateful Dead pack, listing song titles but not a release date. We'll have to wait for official confirmation from Harmonix on the release date of this pack. 

Confirming the leak from a few weeks ago, we will be getting 3 Steve Miller Band singles for Rock Band next week.  In addition to the two tracks that leaked ("The Joker" and "Space Cowboy") we will also be getting "Take the Money and Run." Additionally, there will be 5 more singles from artists including Godsmack, Rob Zombie, and Mute Math.  All tracks will be available for $1.99 (160 MS points).

The full list of tracks is after the break.
