^ except for eminem, i hope your joking... oh and you too. you are ill

every good rapper, mainstream or not, has his or her own rap qaulities which in some ones mind may be suitable to give them a spot in the top 5... but since i dont like comparing mainstream and underground, cos theyre heaps different, ill make 2 lists:

mainstream:
1/ Pac
2/ biggie
3/ eminem
4/ nas
5/ jay-z OR rakim

underground:
1/canibus (i hope he still counts as underground)
2/ copywrite
3/ aesop rock

i cant really decide from the other underground ones.. most of them are equally dope in their own way

and for those who put bow wow and nelly in there lists.... <rips hair out in fury>...
