Youtube covers are really the most boring this allowed to exist on the internet, especially ones like this. If not for Diamonds being such a huge hit she would've found another pop ballad to structurally bastardize and over-sing. Good job on them bathing the entire recording in reverb though, it's almost as if that dorm bedroom leads into a chapel hallway.
Rihanna's version is the only version tbh. None of these histrionic oversung covers by overzealous kids with rudimentary singing talent and zero original ideas of their own.
That pianist is cute though.
Yeah she has a good voice but the way she chose to sing it and the arrangement is just 
She should perform this.
