Figure I'd make another post, even tho no one has responded yet about Rock Band. Here's a good up-to-date thread
for reference to past/future DLC. Since everyone has their own tastes it may be hard to always agree on things. Personally, I'm more interested to the heavier tracks. This Thursday's Thrash Pack is something I'm strongly considering. A few of the past artists I would consider: STP, Skynyrd, QOTSA, Rush, Oasis, and Iron Maiden.
