You have multiple bad takes here.
- PLENTY of people have tried to sound like Jay
- Having biters is NOT the end all be all of "influence"
- This notion that Jay was Big's "lil homie" ala Memphis Bleek is revisionist history.
As for the thread, both rappers are very impactful and influential overall, but I give the edge to Jay, and not just because there were several jay z clones.
Nah he has plenty of influence and impact beyond that.
Just because nobody is trying to re-create his formula (while being black I mind you) does not mean he hasn't influenced Hip Hop, specifically the art of rapping. Some of the biggest and critically acclaimed artists right now have Em in their DNA. Expecting it to be 1:1 is skipping over the fact that Eminem is really an undeground rapper who got to go mainstream due to white privliage. Kendrick/J Cole couldn't run with the formula that made Eminem and be successful, but the influene is stll there. Nobody is going to credit him for the underground rappers like the Hopsin's or the Earl Sweatshirts or even battle rap as a whole because they don't have a lot of mainstream appeal or pesence.
If you think Eminem had no impact on how people rap or battle rappers being able to make a career without even really putting out music like that, you might be on the spectrum, or a hater.
