Japanese Rock can be super sexy! Unlike Americans Rock, were they just look mean and creepy.

Sexy men ;p

For example 'The GazettE' there heavy metal or Punk rock and there super sexy! Plus all guys ;)
Their music videos will just make you think "...Sexy, sexy, sexy, sexy... SEXY!"
  Now I hate rock... Like a lot. but, the 'The GazettE'. What ever they do, they make it seem awesome. Or their sexiness makes you whats the video XD

American's Rock

Creepy, creepy, creepy, creepy! When they sing they just sound like there screaming. I don't have much to say about the American versions... But they sound like they're screaming and they are not hot.
