you dudes think rappers are supposed to stay popular forever.

i guess this is a product of the new secret society era where rappers stay on top, even if theres no demand for their music.
to answer the question:
1.) his music fell off drastically after GRODT
2.) 50 was no spring chicken. the vast majority of his quality work is underground, and he was underground for years.
3.) the blatant sellout music he was putting out chased away alot of his genuine fans, and left him in the same predicament as jarule. and the non-sellout stuff wasnt of high enough quality for people to stick around.
4.) again. he had his run. ITS OVER. thats how the game goes. or how its supposed to go.
5.) he pissed off too many people in the industry, including his own handlers. otherwise, he would still be around putting out terrible music while still being shoved down our throats. just like jay-z, kanye, tip, wayne, etc.
