Rock Band will debut exclusively on 360 with 84 songs on the disc which are all original master recordings, including Bob Dylan, AC/DC, Megadeath, Modest Mouse, and way more than we could list here (we'll update when we can). Plus all the DLC from the first game will be compatible, and
most of the tracks from
Rock Band 1can be ripped from the disc, meaning no disc swapping. All in all, that means that when
Rock Band 2 launches it will have over 500 available tracks.
