i would pick ayu but kelly is a close second and also i have one to add to the list Because of you by Jolin tsai and by the way who is keith martin

I like ayu and kelly.I don't like keith martin!!!

By the way..whos' Keith Martin ????

It's tough.. usually it depends on my mood by I love Ayu's and Clarkson's.

Ayu's version is my favorite but I like Kelly Clarkson's as well.

I really don't know, because I love Ayu's, of course, but Kelly's one is wonderful as well! So, I'd rather not vote =P

Anything but the 98 degree version.

eeew keith martin. because of you by keith martin is a really popular song here in the philippines. it's so popular that a lot of other artists re-sung the song and they even made a movie with that song as its title and theme song. keith martin is some black american dude who is always in the philippines, since i guess he's popular here, and not in his own country.

anyway, i liked the song at first, but it became old really quickly. kelly's and ayu's because of yous are way better, personally. and my pick would have to be ayu's of course. beautiful beautiful rockin song

Because of You is one of my favourite songs from Ayu so I chose that one, but Kelly Clarkson's Because of You is also really beautiful :)

"-_- there's absolutely no competition here. ayu's because of you is da bomb.
