I actually listened to Gakupo and Kaito duet version first (the embedded video here), then proceeded to hear the four Vocaloid version (Miku, Rin, Kaito and Len), then the rest of the versions. Surprisingly, I like almost all of them (forgot which one I didn’t like as much). Click on the link if you want to know more, but don’t say I didn’t warn you, it’s a Japanese site. ^^;

Maybe I’ll touch on a few more of the other Vocaloid songs that I like sometimes. xD
