Rihanna has a proven track record so obviously she's going to get all the good tracks first. And Calvin wrote and produced the track by himself that he banned her from using. If Rita wanted to use it so badly she should have contributed some production or writing but she didn't, so..

The label has no jurisdiction to force Calvin to give
his track to someone he doesn't want to.
Sounds like she's trying to blame everyone but herself for her failure.
