After watching all videos posted I've come to the conclusion that, IMO, there's definitely some truth to what she's saying but there seems to be more bitterness and narcissism in her story than facts.
According to her she was the inspiration for all these other acts and everyone from The Roots, Jill Scott, John Legend, Erykah Badu, Truth Hurts, etc. stole from or were inspired by her in some form or another.
She seems to view her participation in Jay-Z's unplugged as more of a favor to The Roots as opposed to a look out from them. She even asks in one video what it would have been without her?
She then continually airs how who Jill, Erykah, Black Thought, Common, etc. have fucked or who they are fucking.
She even suggests that The Roots deceased manager/producer Richard Nichols (in the last video I believe) was practicing some type of black magic shit which is why she quit fucking with him.
She admits they showed up for Malik's viewing but shits on them for not staying for the funeral (which a lot of people including me do.)
She continually mentions Malik B as the reason she's calling them out but instead is only talking about who she and they are fucking while also speaking to her greatness which she feels that all feared her for and cites as the reason they have killed her career.
Again I don't doubt that there is some truth to what she's saying but if you didn't know anything about her you'd swear you were listening to someone as influential as Diana Ross or Aretha Franklin
