A U.S. blogger accused of posting leaked tracks from the long-delayed Guns N' Roses album Chinese Democracy has pleaded guilty in Los Angeles to a criminal charge of copyright violation.

On Monday, Kevin Cogill admitted that he had posted nine out of the 14 tracks from the highly anticipated album to his online blog Antiquiet in June.

The rabid interest in the material, which Guns N' Roses frontman Axl Rose had been working on for more than a decade, crashed the site.

The album was officially released late last month.

The 28-year-old Cogill, who had initially entered a not guilty plea to the federal charge in October, said Monday that his decision to post the material was not motivated by financial gain, though he admitted that "all the attention helped me."

As part of his plea deal, Cogill must co-operate with any further investigation of the case, including perhaps disclosing how he got access to the leaked tracks.

He faces a maximum of one year in federal prison, as well as a $100,000 US fine and five year's probation. Sentencing is scheduled for March 3.
