there's always been a fair amount of fake people in the music bizz
this will never change
many "real" producers aren't even mentioned, but do get paid (or are ripped off)
I happen to know for instance the guy who worked in the studio for R&S recs back in the day (he's a good friend of mine) and he did stuff for dave angel, joey beltram, ... the very first productions of dave angel were actually done in his appartment... but he never got credited for it... because it simply was his "job", so no author rights or anything
the music bizz can really suck sometimes!! it's full of assholes
