Interesting thread here! I'll have to go through those PV's! ^^
In the mean time, I'll share some of my own as well, even though I don't know that many... >_>;
D'espairsRay - LOVE IS DEAD
Kanon Wakeshima - Suna no Oshiro
Zebra Queen - NAMIDA ~Kokoro Abaite~
SS501 - Love Ya
and... I can't think of any more at the moment! Dx
