Ariana Grande performs ‘Just a Little Bit of Your Heart’ at Grammys...

Ariana Grande actually has a good voice but there is not much dimension to it. I think the issue here is that it lacks depth and sincerity, which is one thing she doesn't have over a Mariah Carey. The orchestra was a nice touch to the Harry Styles penned ballad. 

'Just a Little Bit of Your Heart' is lifted off her latest album 'My Everything.'
