The Recording Industry Association of America (RIAA) has dropped its prosecution of online music retailer AllOfMP3.com.
The RIAA said it is ending its action because the Russian music download site is no longer operational, saying this means the music industry group has succeeded in its attempt to get the site shut down.
The Russian government shut down the site last year when US officials described AllOfMP3.com as a barrier to the country joining the World Trade Organization.
A new site, called MP3Sparks, has since sprung up in Russia, this site allows former AllOfMP3.com users to buy tracks using their existing log in and password details. The RIAA has not begun action against the new site, but says it expects Russia to take that site down also.
