Apple was today hailed for pioneering a "listening revolution" as it prepared to celebrate a decade of iTunes.
The music store, which started out more than a decade ago with 200,000 songs, reached its 25 billionth download earlier this year.
Since its launch on April 28 2003, iTunes has accrued a catalogue of more than 35 million songs and has around 435 million active account-holders across the world.
On average, more than 15,000 songs are downloaded every minute and according to the technology website Pocket-lint, it would take more than 140,000 years to listen to every single music download available through the famous store.
Gennaro Castaldo, of HMV, said the music store - along with the iPod - had "undoubtedly" played a major part in changing the way consumers discover and listen to music.
