Harmonix has another Rock Band track disc heading our way, according to an ESRB listing.
It's the Rock Band Track Pack: Classic Rock for PS2, PS3, Wii and Xbox 360.
I'll feature The Steve Miller Band and The Dead Kennedy's by sounds of the description posted below -- without the censoring:
Some song lyrics can contain expletives (e.g., "damn," "ass," and "bitch") as well as references to violence (e.g., "Billy Joe shot a man while robbing his castle" and "Then your head is skewered on a stake.") and allusions to drug use (e.g., "I'm a midnight toker" and "…sit around the house, get high, and watch the tube").
Expect it to include 500 songs and likely to be priced the same as other track pack discs -- $29.99.
