The music from Prince William and Kate Middleton's wedding will be available to download just hours after the ceremony.
The couple will tie the knot at London's Westminster Abbey on April 29 and now after watching the nuptials on TV screens across the globe, punters will be able to purchase 'The Royal Wedding: The Official Album' from the internet to relive the magic.
The album - which will be packed with recordings of the London Chamber Orchestra and the Fanfare Team from The Central Band of the Royal Air Force - will be on sale in shops from May 5 and industry experts are expecting it to be a huge hit.
HMV spokesman Gennaro Castaldo told Britain's The Sun newspaper: "We're expecting huge demand for what will prove a collectible recording and piece of royal memorabilia. I think we could well be looking at the first ever Number One royal album.
"And if enough people start to download their favourite parts of the service 'X Factor'-style, then you could have a situation where the royal couple find themselves on the top of the singles charts as well."
The album deal has been signed with Decca Records, who released a vinyl copy of the music from William's parents, Prince Charles and Princess Diana's 1981 wedding as well as Diana's 1997 funeral.
