ok honestly, what if is prob one of the most gorgeous songs ever, and radio play would kill it, because the none coldplay fans will be all over it and kill it! same with square one,...yet a message and SITS is kind of a more mellow side, which would show another side of Coldplay rather than the fast Clocks/Talk singles and the slower gorgeous Scientist/Trouble/Fix You...so its a bit odd...i honestly thing how you see the world, though not an official album track on the regular X&Y only the lucky japanese verion,..but i think that would actually be a good single. .. iduno but definetly the B sides are the most important thing :)
