Apple's iTunes Music Store has signed an exclusive deal to distribute digital versions of some Oasis tracks.

Similar deals have been signed with other UK music operators, with different operators offering different exclusive deals.

Apple's success in signing Oasis to its service means that a new selection from the band's catalogue will be made available each week in the run-up to Christmas, with 'Definitely Maybe' available now.

This week's free 'Single of the Week' comes from new artist, 'Smadj'. Smadj is a Tunisian artist, who combines sounds from that culture with electronic dance music, latin, jazz and oriental elements. He works with Talvin Singh, Mehdi Haddab and other established artists. The single is available for free download.

Additional new releases include Eminem's 'Encore' and new Faithless EP, 'Miss You less, See You More', and Franz Ferdinand's self-titled debut album.
