This week's iTunes 'Single of the Week' comes from Californian girl-rockers, The Donnas.

The single, 'Fall Behind Me', is described as "tearing out of the gate with a screaming guitar riff that crashes into the track's driving drum-line and kiss-off vocals". The single is taken from the band's new album, 'Gold Medal'.

iTunes Music Store is also offering a selection of exclusive and pre-release tracks this week, from The Prodigy, Gwen Stefani, Busted, Cliff Richard, Anastacia, and Travis.

Also available now through the UK store is a selection of iTunes Originals, which feature live artists performances and in-depth interviews. Artists avaialble include: PJ Harvey, Alanis Morissette, LL Cool J and Sting.

However, key independent artists, including Franz Ferdinand, remain unavailable through the store.
