7 TUNES; This week's essential download tracks.

DIZZEE RASCAL Dirtee Cash We're inundated with dodgy covers of old dance tracks at the moment, many of them dull and uninventive, but this latest effort from the young British rapper is genius. Shows how covers should be done.

DAVID GUETTA FT. ESTELLE One Love The latest collaboration from Gallic dance guru Guetta, this time featuring American Boy singer Estelle. It's more of the same really, an upbeat commercial dance number that will be a big hit.

LILYALLEN Who'd Have Known Lily Allen sounds all cutesy on this track that sounds uncannily like Take That's Shine. It comes with a creepy video where she's obsessed with Elton John and kidnaps him.

LADY GAGA Bad Romance The outrageous artist - in every sense of the term - unveils this new song as part of her practically new album. It's much as you would expect, a big chorus topping an electro monster.

THE LOUCHE Louisa This north London band are full of hazy laid-back harmonies and this track is an elegant dreamy landscape about a girl always just out of reach. Wonderfully melodic.

LITTLE BOOTS Earthquake More synth pop from the Blackpool-born popster. Her sweet vocals build up to a euphoric track that's as shiny as a new penny with a dancefriendly Euro-pop sound.

PARAMORE Brick By Boring Brick Paramore have won fans all over the world with their energetic rock sound and punky stylings. This new track will win them loads more as it's a surefire hit.
