A lot of people don't get credited on Sugarhill, thats the way it was, Shady people running a shady operation, ulttimately it is why it failed, and similar electro labels all fail.
You can only fuck someone over once!!!! It still goes on in the scene today... I wonder how many current ELECTRO ARTISTS are getting royalties from current Album releases, I bet i can count them on one finger.
Many artists have admitted to me they won't deal with certain labels and companies for fear of being ripped off and even more simply that they will not return any royalties for the small amount of sales there really are. which is a shame.
Duke Booty, didnt get the credit, But hell, Clayton Savage didnt get paid or any credit and he wrote most of the Work PArty Album for Melle Mel and FF after the split with GMF, he has told me the label was well fucked up.
Nothing changes with Electro , That is why many artists got sick of getting ripped of in the late 80's and went over to House or Bass Freestyle music where money could be made from publishing.
Many young kids these days don't even understand what label copy / Royalties are, let alone a publishing deal, and that is why they will continue to get ripped of, and get fed up.
One word of Warning, Never ever pay a label or publishing company upfront for Inclusion on a release or even Advice. If they want to sign you, they will pay you upfront, with a proper Advance and contract of Schedule of royalties.
