Um no. Ayumi Hamasaki sold 450,000 copies with each album. If she wasn't such an album *****, she'd put it all on one disk. All this did was have the same 450,000 ppl by the two copies each, as exemplified by the almost exactly duplicate sales total. I'm sure plenty of other artists could sell 900,000 if they had a ignorant fan base who was willing to buy one cd for the price of two! LMAO. ;p
On other more important news, Utada Hikaru's "Flavor Of Life" sold 271,000 copies as a SINGLE.
