ayu's page at russian itunes is just a mess. I hate mess! %)
there is evolution single by the name Ayumi Hamasaki with 9 tracks, that costs 109rub
https://itunes.apple.com/ru/album/evolution/id75662105
and there is evolution single by the name 浜崎あゆみ with 10 tracks, that costs 69rub
https://itunes.apple.com/ru/album/ev...n/id1001876736
most of singles are doubled, Ayumi Hamasaki don't have instrumentals, 浜崎あゆみ have instrumental and more cheap
what? why?
