Thanks. Looking into it a little I've seen "1,500 song streams from an album were treated as equivalent to one purchase of the album." The HARDCORE fan base that couldn't wait a day or two is so low, the fans aren't what botched the sales on this one.

"Billboard continues to publish a pure album sales chart, called Top Album Sales, that maintains the traditional Billboard 200 methodology, based exclusively on Nielsen SoundScan's sales data" I'm not sure which chart these numbers come from but I just don't think piracy from album leaking a day before is worth a guilt trip over.
