Honestly E-40 would have to be an idiot to quit.. I mean his last albums both debut in the billboard top 200 so he is obviously making money still and the song "Function" was huge I heard people slapping it like crazy when i was out in Hawaii and motha fuckas in Hawaii dont even be listening to rap that much usuallty just reggae and shit.. there is obviously still a huge market for his shit.. he has remaind relevent for 25 almost 30 years.. Name any other rappers who have done that.. their isnt much... You say he raps about the same shit and doesnt change his style? why would he change if it is working for him?... when most rappers change their style they lose fans... Brotha Lynch's season of the siccness did crazy numbers for an independant album after that he didnt do as much of the cannobolistic crazy phsyco raps and didnt sell as much but now his last three albums he is back on the weirdo serial killer type of rap and is doing real good numbers... I used to like Tech N9ne, Andre Nickatina, Messy Marv, Master P but they have all changed their styles from 10 years ago and i do not like most of their newer music... it is still workin for him why would he quit or change his style
