@mikecavs=Didn't she mention a few weeks back that the composer or arranger or something was H/\L? I know jack all about music actually, so have no idea who does what
As I said in the last thread, I agree that it is too early to tell based on a 30s preview. The voiceover blocks out almost all but about 8 seconds of pure music so whatever conclusion you come to will be pretty biased.
Ayu HAS done lots of covers. Sotsugyou Shashin, Bold & Delicious, In the Corner and Pride to name a few. There is a possibility this is a cover but we can't say that as a fact yet.
Ayu already gets a lot of schtick about plagiarism from other sites so you'll naturally get people's backs up when it's suggested here too. I do not think a verdict can be reached with a 30s, sketchy-at-best CM.
