Early tupac = Rakim...
Big friggen deal bruz.. Everyone is influenced by somebody.. And anyone who says their not is a liar... New artists can bring an interesting new spin on an older style.. Its still their own music... This is the problem with dudes who are too caught up in their whos who of music.. You think it was a dope call to say "oooh but man yo yo, these guys had that style BEFORE him so naturally they are liek sooo much better and shit" when I'm in here enjoying the dudes music and I could give less than a shit about nine inch nails...
Its natural for an artist to diss another artist when they feel the other one is stealing a large quantity of their fan base.. Even elvis absolutly hated the beatles and dissed them regularily...
And btw....... Nine Inch nails have done tracks with manson before too...
