50's run was not that impressive. It was even a letdown. Dude started running out of fuel after 2 albums (GRODT and the G-Unit album).
However, his arrival in the game is probably the most dominant in the genre. He came like a storm.
*sigh*
50 did 872k in week one for GRODT. short week. then followed it up a week later with another 822k. then did another 1.1M in week one for the massacre. lead singles from both albums were #1 for 9 weeks.
DEBUT ARTIST. first two albums. and yeah, throw on another 9M+ sales worldwide for beg for mercy. what part "a letdown"?
also, he did not run out of fuel. if anything, one of 50's main problems was the exact opposite. he dropped
too much heat while he was on top. he should've been holding onto some of those mixtape records in particular, instead of dropping 1-3 mixtapes every month on top of all those albums. at some point, the quality of the music didn't even matter; people were just sick of hearing from him. and when the quality eventually did drop... then end.
