Harmonix also revealed that the title will not require frequent disc swapping to get the original Rock Band tracks in the Rock Band 2.

Original Story: Adding to a steady stream of Rock Band 2 news, more details about the game were announced today by Harmonix and MTV Games. Available for Xbox 360 this September with PS2, PS3 and Wii releases following later in the year, Rock Band 2 is set to ship with over a hundred songs.

A total of 84 tracks will be on disc, and another 20 will follow as a free DLC pack following release. Combined with DLC from the first game, the Rock Band platform will feature 500 available songs by the end of this year.

In addition to previously announced bands, Rock Band 2 will also feature songs by Pearl Jam, Metallica, Allman Brothers, Motorhead, Devo, Jane's Addiction, Megadeth, Paramore, and Modest Mouse.

The game will also feature "Let There Be Rock" by AC/DC, a music rhythm game first, and "Shackler's Revenge" from Guns N' Roses' long, long, long anticipated new album Chinese Democracy. Also look for Bob Dylan's "Tangled Up In Blue."

Harmonix also noted that in addition to Rock Band 1 DLC compatibility, Rock Band 2 will include a Disc Export Feature. It will give owners of the original game "the ability to export most of the Rock Band disc tracks and upgrade them into Rock Band 2 gameplay"
