Help! Who sings this?

[Coelacanth]

Well I was looking for a Japanese version of a BoA song on WinMX when I came across "I Will Survive" (Japanese Version), I downloaded it curiously to see if it was the original singer. ("I Will Survive" being a disco classic and all)

Turns out it wasn't the original singer and it wasn't in Japanese. I'm 99% sure it's in Korean. Here is the file - http://s48.yousendit.com/d.aspx?id=2...01B1TJNXP47B2Q

Now, does anyone know who sings it? It does kind of sound like BoA, if it is, I greatly underestimated her singing talent. thanks...
