Strange that - Creep is one of the tracks that I always avoid like the plague, because it doesn't even particularly sound like them and has become a kind of MOR sing-along.
Another vote for Fake Plastic Trees, which is one of my favourite songs ever.
I think House of Cards is underrated too. I'm far more of a The Bends, OK Computer and In Rainbows - style Radiohead fan, King of Limbs did nothing for me.
