The copyright of those works still holds water internationally. That's why the labels have the capacity to sue the site. I doubt very much that ALLOFMP3 and this supposed royalty agency is legit. If it was, these agreements would have been in place before the site would have opened. ROMS doesn't appear to have agreements with BMI, ASCAP, SOCAN, etc. which means that their collection is in a vacuum and as such, isn't legitimate on an international level. If they're collecting royalties for the Orb, there's no protocol in place to send that payment to right organization. Surprise surprise! The Russians are selling stuff on the black market.
Don't think for a second that ALLOFMP3 has got an edge on the legitimate e-tailers. You can pay a buck for your album, but don't expect that the artist ever agreed to that.
