For what it's worth, this seller was the source of the first CD, so it's not like he took anything from here and made CDs. Also, it should be noted that the tracks obtained were real.
Quite frankly, there's no way of knowing how many of these CDs may actually exist as they were meant to be internal WB property. In the past, we've seen multiple copies of other internal acetates and no one bats an eyelash when it comes to seeing them listed on eBay for sale. This one strikes a nerve because of the price paid for copies of the CDs, but as I've said before, the buyer sets the final price in an auction setting, not the seller.
