Kanariya remix ID

I just found out that the original Kanariya was the one found on the LOVEppears CD. That was 'the slow one' and I thought it was a remix the first time I heard it...

Well, the very first version of Kanariya I heard was this one: http://download.yousendit.com/79D5ECBB1EA6EF9B

and I always thought it was the original simply because it was the first one I ever heard...but now I want to know if anyone knows what version that particular one is. I think I saw something about it being a radio edit, but I'm not sure.
