I pretty much agree with all the replies in this thread.
The thing to really think about is: Who said rap music should have an age limit?
2Pac died at age 25 and pretty much set that type of mind frame IMO. The way he flauted being young etc etc, but failed to realize those that came BEFORE (key word) and paved the way were also youngsters (17 through 21) when they were being heard on radio stations across this country. The likes of LL Cool J being one of the major factors in this Game (like him or not).
Picture Snoop Dogg dying right after he droppped "Doggystyle." People would have never seen Snoop grow in this music business (whack or not...this is not about that), and continue to do his thang in it.
Jay Z, Nas, Dr. Dre, 50 Cent, P. Diddy and the list goes on...
and like most replies: If the music is still HOT and you enjoy doing what you doing...
no reason to stop because society say's so...be a menace!
