Look, even with Tinashe's limited singing ability she's just average at everything at best and thats why she'll never really pop off. She doesn't possess what all other artists annoying or otherwise posses and that is an image/brand. Much like Rita Ora she's okay vocally and has a few catchy songs, but the media and girls in general like an image, a look, a vibe that they can latch on to and emulate. Tinashe doesn't have that she has video looks and then everyday looks but no signature look, era look hairstyle make up.... and much Like Ora she seems to be dressed for occasions with little consistency, but the only thing that Ora has better is a team who keep her out there and that started off by Roc Nation having faith in her limited a$$ and opening doors and getting her contacts that continue to this day.

As for this Rihanna Joyride poaching situation. She said that she's still recording which means the album was never complete. I don't believe that after the song was taken that you didn't just rename the album and replace the song but over a year later you're now saying that you have the song back and your still recording... then the music was never that great and the record company doesn't believe in the product.
I dont dislike Tinashe, i could take her or leave her, her album had a few good tunes and her mixtape also but i have no belief that this album will be a masterpiece and that she will retain her deal after this doesn't do well as it must be costing the label money.
Good luck to hr though.
