Not everyone's a winner at the Grammys, especially when there are 82 categories. But away from the brassy gramophones you can be a loser and a winner. See Taylor Swift. She didn't win any actual gongs this year but her head-banging moment will be remembered on the internet for at least a day. Pharrell may have performed on stage with Stevie Wonder, Daft Punk and Nile Rogers but it's his bizarre Harry Potter sorting hat that won fashion. And Trent Reznor may have swallowed his hatred of The Man to perform on the night but his 'fuck you' tweet to the organisers was probably the most controversial moment of the whole ceremony.
