that comedy shyt and dark humor with the level of production and stamp by the dre brand is what helped propelled Eminem..u got a point, but we might of never got the silly type music from Em with Fat Joe instead of Dr. Dre & Interscope. we'd probably get more of his underground hip hop but he def wouldn't have been as popular. it's hard to say really. Interscope is known to bring artists to a whole another fanbase.
eminem on east coast beats would have remained between more obscure compared to the success he gained..
fat joe wasn't popular as many thought he was..Big Pun did his shyt, successfuly.l
