The future of the 99p music download looks bleak because of a change in VAT rules as the Treasury bids to reclaim more than £300 million in tax from tech giants like Apple and Amazon.
Chancellor George Osborne announced in last week's budget that multinational firms will have to pay the UK's standard 20% levy on all digital sales to British customers from next year.
Both Apple and Amazon currently benefit from a lower VAT rate on music downloads from their online stores like iTunes and Google Play by operating out of Luxembourg.
The changes are expected to see the 99p rate for a single download rise when the new rules take effect in January to end the loophole.
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.
