A man has admitted being involved in a £500,000 fraud in which he used stolen credit card details to buy his own songs on iTunes and Amazon.
Lamar Johnson, 19, from Wolverhampton, was part of a group accused of obtaining royalties from the sales.
They allegedly downloaded the songs 6,000 times in 2008 and 2009. Johnson admitted being responsible for about 2,000, Southwark Crown Court heard.
He was remanded in custody after sentencing was adjourned.
Prosecuting, Helen Malcolm QC, said Johnson, of Stowheath Lane, used "compromised credit card details" in order to gain royalties from the sales of the songs he posted on the websites.
Johnson, who is currently serving a five-year prison term for causing grievous bodily harm, is the youngest member of the group of 11 other defendants accused of downloading the songs between January 2008 and June 2009.
He pleaded guilty to one count of conspiracy to defraud at the court on Thursday.
No pleas were entered for the remaining defendants who will appear at the same court on 25 January.
