Is Ayumi just a big copycat?

[marty]

I don't really think "cover" is the right word for it... She just paid someone for their composition, like she always did. European or Japanese, it's the same, and it really doesn't matter if someone sang on the same melody before, if I paid it's rightfully mine.
It's like saying Girls Generation stole Run Devil Run from Kesha just because she sang the demo firstXD
