I wouldn't say she can't sing either, because she clearly can. But I do think she needs better diction. Maybe she does have it, but it needs to be crisper. Perhaps she does pronounce the ends of her words, but they just get lost with all the instrumentation, so she needs to make it sound more distinct. It really does sound like Skyfow, Crumbows etc. Or maybe Skyfaux? That's all I can hear now. And I agree she should've belted it towards the end like Shirley Bassey. She tends to sing that song pretty much on the same level throughout and needs more dynamics.
