Dizzee Rascal has unveiled his new Olympic single – scroll down to watch the video for it.

The track, titled 'Scream' – which is one of five tracks that will soundtrack London 2012 - will also feature Dizzee's protégé, vocalist Pepper.

Other artists who have contributed songs to the sports presentation programme of this year's Olympics are Muse, The Chemical Brothers, Delphic and Elton John and Pnau, who are all part of the 'Rock The Games' programme.

Muse have provided the main official song of the London 2012 Olympics. The track, which is titled 'Survival', will be played when athletes enter the stadium, in the lead up to the medal ceremony and also as the theme for all international TV coverage. Scroll down to listen to the song.

The soundtrack to the London Olympics' opening ceremony will go on sale to the general public shortly after the event at midnight Saturday (July 28). The music from the ceremony will be released digitally and feature new tracks by Underworld and songs from artists who will perform on the night from the Olympic stadium.

Titled 'Isles Of Wonder: Music For The Opening Ceremony Of The London 2012 Olympic Games'[/b], the album will see a physical release on August 6. The opening ceremony album takes its title from the 'Isles Of Wonder' speech in Shakespeare's The Tempest, which the event's director Danny Boyle cited as the inspiration behind the event.

As organisers of the games want to keep who is performing at the opening ceremony a secret, Decca/Universal – the record label behind the release – have kept the tracklisting a secret so as not to spoil any potential surprises. However, last month, a leaked document revealed Arctic Monkeys and Muse may appear on the soundtrack.
