2. 'Fix You'
Coldplay's third album, 2005's X&Y, is generally considered to be the weakest of the band's five records, but it did produce "Fix You," one of their most iconic hits. It's a polarizing tune – while it's obviously popular enough to reach Number Two on this list, it's usually the first tune Coldplay haters mention when they rail against the band. Even if you despise the song, you've got to admit that it's used to great effect in this clip from an episode of The O.C. in which one of the show's villains drops dead from a heart attack in his swimming pool.
