See, I'm one of the people who do think that Jolin "copies" (whether it's copying, strongly influenced, or flat out coincidence, I can't say for sure because it seems like it may be different cases a few times), but on the other hand...it's probably not her fault, right? I mean, it's rare for musicians to have the main say in things like costumes and PVs. Just because Ayu has her say, along with a few other really big artists, doesn't mean everybody gets this privilege. I don't think Jolin Tsai has made it that far yet, to be able to make those decisions, so I don't really have a problem with her for the "copying." I'm more bothered by her singing, lol.
(No offense to the fans here. I just don't like her singing, hah.)
