Listened to this song and a few other Coldplay songs after this break up I had. Hard to say whether it actually helped me get through it, but it certainly felt like it matched my mood at the time. Just now I'm listening to this song again, the first time since (like two years at this point), and I'm glad to say I don't feel any residual sorrow. LOL
I find it hilarious that I got a Coldplay song through Radiohead Radio. :P But to be perfectly honest, I'm one of the few Radiohead fans who likes Coldplay. Heck, I love a lot of their songs. This one is a particular favorite. Gotta love Will's drumming here.
