Found out the reason it no longer works with Virgin Digital and how I was correct in my theory on how
MusicMatch converted it.
#1) MusicMatch's converter is like real time recording but at a much fast speed ( don't ask me how )
#2) Virgin Digital Licenses contain "Collaborative Play Not Allowed" While napsters still do not. Collaborative play means no player but WMP can play them while recording or something... I'm not 100% sure but
MuvAudio still works.
