Sorry folks, I've been delinquent. My Rock Band DLC spreadsheet should be updated through, I think, last week's content (prior to the no-longer-exclusive-to-Europe DLC).
I took out the formatting for master tracks vs. cover bands because it didn't seem to be working, and I added tracks that I don't personally own (now that I can get that info easily from the Rock Band Store).
P.S. I added a link to it on the left, so that in a couple of months when this isn't on the front page, lol, you'll still find it easily.
