I knew Shania's worldwide sales were huge and haven't some of her CDs gone diamond in the US too? It is good to keep stats like that in mind when we rave about Breakaway's success or Some Hearts'. I think Eminem or 50 Cent had an album that sold almost a million copies its first week a year or so ago. As impressive as triple and quintuple platinum are, those awards leave a lot of room to go to catch up with the huge stars in the industry.
You mentioned Asia, and I am not sure who controls distribution there. I think it is considered separately from Europe.
