Whatever People Say I Am, That's What I'm Not (hurts to type this!) was the Arctic Monkeys' best. It's not perfect - Mardy Bum and that Vampires song are a bit childish - and drops some lyrical clangers, but thinking of their age, I can forgive them. There's a sense of likeable ultimate chaos about it. 8/10.
Everything since has been a bit 5/10, pipe and slippers.
