I'd like to see the receipts of her being a great 'technical' singer. I doubt the girl even possesses a vocal range above 3 octaves but that's a discussion for later. Her writing credits didn't really save her debut album, did it?
However, I do think Zendaya has a far greater appeal than Tinashe and is easily a better performer considering she's so young.
Yeah, okay.
And her writing skills helped 'Aquarius' become more critically-acclaimed than anything ever released by Rihanna or Cassie or Ciara. So she must be doing something right.
