Hm... I'm affraid I'm not familiar with Cold Play. But don't worry, people have told us we sound "like early The Cure" before and I couldn't name you a Cure song if my life was at stake. :)
My biggest influence is probably Hank Marvin, he's the reason I started playing guitar. I try to listen to as many genres as possible from folk-rock to new age, and one of my biggest regrets of life is that I'll probably never be able to listen to all the music that's out there that I'd like, either because it was never recorded/got lost, I'll never find it, or doesn't exist (yet). Uhh, getting a little philosophical here...
