Monday, Harmonix announced its new music game Rock Band. Promising to be four times the goodness of Guitar Hero, Rock Band enables a quartet of players to form a group and play to the master tracks of a variety of rock artists. While IGN has made a Guitar Hero Fantasy Set List in the past, they decided that a new list was in order, centered on the idea of great bands. After all, it's not just about the guitar anymore. IGN feels these ten bands give a wide breadth of style and have an excellent library of songs made for rockin'.
