Wikipedia's "Albums claimed to have sold 20 million or more units"

yeah, I admit to a few cheeseballs on here, but when it comes to Shania and Britney, I’m out.

Depends on how you define ‘consume’ I guess.

I don’t think you have to actually purchase the album. If you can listen to a friend’s copy just once, wouldn’t that count:-)

Robert is correct, you can just borrow a friend’s copy. Still, finding friends with half that crap will be a chore.

You may need to hit some thrift shops, listen, then throw it away.
