all i can find is what you found Mark, whoever owns the rights to the tracks goes through this "ROMS" group. on mp3skyline it does clearly state that they are affiliated with ROMS... which i doubt very much. From what ive heard of the mp3's (not all but a few) they sound like they were recorded right off vinyl.

Id say if you do persue this, the site will be taken down, i doubt very much that you will get any money back off them.
