ROMS is the copyright enforcement agency in Russia. They take the payments for royalties and then distribute them to the artists in question.
The "issue" (as some (read : RIAA) may say) is that ROMS does not charge as much as everyone else does, which is why we can get music so damn cheap! The RIAA would have you believe that the artists don't get anything, when in fact they do, it's just what ROMS believes they should get, not what they want.
