This is SUCH a disaster. I don't understand why Tinashe keeps getting pushed back, she has the IT factor. I seriously hope she does something to violate her contract with R*A and gets dropped.
I also believe Rih didn't know this was her song, producers market their best beats to the bigger stars. I am sure Hit Boy didn't go to Rih and say "This is Tee's song, but you can have it". He sent it to her with no prefix, probably along with a few other tracks. Producers get their coins off of how well the song does, they are not interested in loyalty to the original artist who recorded it.
