This just might be the definitive Coldplay song. The song that makes Coldplay ‘Coldplay.’ That piano line is unmistakable and irresistible. Don’t even try to front. I don’t care how painfully hip you are, you know you like this. And you know that if you were at a Coldplay show and Chris Martin started playing that piano line, you would go bat crazy. VH1 was right on in naming “Clocks” one of the Greatest Songs of the 00’s. It’s a standout on the band’s sophomore album A Rush of Blood to the Head. And as brilliant and iconic as that album is, that’s saying a lot.
