Would put out a bloody good greatest hits compilation, wouldn't they? Even if the albums are fairly hit and miss, they have certainly been one of the better singles bands of the last decade, and even going by chart position alone it'd be great.
Obviously, all the people who think they are dull, turgid, over-earnest and generally shit, this thread is not for you.
Here would be my tracklist thus far into their career (a fairly obvious one):
In My Place
Speed Of Sound
Viva La Vida
Lost (the Jay Z version)
Every Teardrop Is A Waterfall
Plus the next couple of singles from album 5 and maybe one specifically recorded for it.
Barely a skippable track there imo.
