I chose vet. It could go either way, but if you say 50 is legendary, i wouldnt say its because of his music. He made/creates good music, sure, but I would consider 50 Legendary status more for how hes done business. From the Mixtapes, to causing controversy to get noticed, to making moves very quickly outside of music.
Dude released GRODT and immediately capitalized off of it like he knew his time was going to run out. Got G Unit records, distributed through interscope, release the crews Group and solo albums (that first round they ALL went platinum, even yayo), quickly jumped into movies, then started getting into all sorts of other ventures.
All the while, he was in serious beefs. First with Supreme then with Henchmen.
Dude should write a memoir series from his childhood all the way through today where hes comfortably a millionaire. Im sure each book focusing on a different decade of his life would be interesting as fuck.
