Twelve people are to face court accused of using stolen credit cards to buy their own songs on iTunes, police said.
A gang is alleged to have created about 20 songs and uploaded them to be sold on the iTunes and Amazon online sites.
They are alleged to have used stolen or cloned credit cards to buy songs worth £469,000 and cream off the royalties.
Raids took place in London, Birmingham, Wolverhampton and Kent. Twelve people are due at City of Westminster Magistrates' Court on 15 September.
The suspects were questioned by members of Scotland Yard's e-crime unit after the raids.
The move followed a joint investigation with the FBI into claims that an international criminal gang targeted the two online music stores.
