A BEST: why the high sales?

[gakkun]

I don't think advertising was the main reason why it sold so much..best albums sells well because people who weren't normal a fan also got a copy of the album. And with an artist as famous as Ayu..well, I'd imagine anybody who didn't detest pop music would've got it. Of course we can't ignore those hard-core fans who had to get all the covers/variations etc. =p
