That happens when any artist dies but you can't deny that over a decade later Aaliyah has a true hold over the people and still gaining new fans, her promise was clear to most people that's why. T-Pain is a nobody that's why he's releasing mixtapes now. And Aaliyah was an established solo act before Beyonce got her foot out of DC, trust me if she was here they'd both have some similarities but definitely in their own lanes musically, fashion wise and film wise.
IF anything Rihanna and Aaliyah seem like similar artists to me, Aaliyah wanted to try alternative rock sounds on top of continuing the futuristic urban sounds she was known for and was going to go far in film and modelling. Have a SEAT T-PAIN and don't use Queen's vocals for your FLOP messes then, he is so unappealing. But that Girlfriends track is a damn mess in itself out of all songs to sample
