Except that some smaller lables, and most bands aren't set up to report sales to SoundScan.
This kinda puzzles me. It can't be all THAT hard for a label to get hooked up for Soundscan reporting, for CD sales at concerts or wherever.
Heck, if Dancing Ferret (goth/underground label, r.i.p.) can do it, I'd think any of "our" metal labels could, too.
