what's in the bag, ma'am?

I recently read a survey saying that cd sales are up in the U.S. With all the pissing and moaning from RIAA about music being traded illegally.this seems to be counterintuitive. I would, however, like to see a survey that reveals the rate at which cd's have been shoplifted over the last decade. My gut says it will have gone down...but RIAA was wrong so I don't see why I couldn't be.
