dogcat, that number is NOT based on any fact that I know. I don't personally know how big UMG's library is. I've heard five to seven million, but really don't know if that includes all their foreign labels or not. I was just trying to be conservative. They also said their "digital" library, so I also took into consideration that meant fewer songs than their entire library. Don't get stuck on the number. It was just for illustrative purposes.
