^haha, forget wut I said, but I uno, I follow T.I.'s career and T.I. Vs. T.I.P. is a project he started years before his becoming famous, so it's kinda different...the only way I can explain it is to use Utada, but I don't think you guys are familiar with it. Previously, she was Cubic U, then she was Utada Hikaru, but then there was a later release of Cubic U material, which technically one could say is "Utada"...but...
yeah, so that's the best I can splain it, but if still doesn't make sense, my bad. ;p
Yeah, something like that. Artists, particularly rappers, when they change names, they get a different discography. It's just odd that T.I. went back to working on previous work, so it sort of makes things confusing. haha, don't worry about it, I shouldn't have mentioned it.
