People going with group think. I based my answer (2Pac) on personal impact in my life, not anyone else's.
I can't get rid of Nas. He made One Mic and Made You Look.
I can't get rid of Jay-Z. He made Lost One's.
I can't get rid of Ice Cube. He made a lot of conscience records and he's one of the few artists that I bumped later on in their career (I liked the 'Laugh Now/Cry Later' album).
2Pac was before my time. Never really got into him, although I liked a few of the records I heard. So Many Tears, Brenda's Got A Baby.
I'm also one of the few people who don't like Biggie at all. Although I did bump 10 Crack Commandments.
