I think both PVs have a similar sexiness and edginess to it that makes gay men wanna go straight.
Kudos to Ayu for trying out being sexy, but I think ECSTASY has got a better PV here... the changes in between scenes are a thousand times better than Sparkle. Sorry Ayu, if it was Wakaru Takeshi who directed Sparkle instead of Kazuyoshi Shimomura, you know I would have voted for you!
