Love how she put so much charisma and personality into that performance. However vocally, I'm gonna have to give it a thumbs down. She's a fantastic singer but she can sing better than that. She cracked way too many times and was putting too much tension on her belts. I guess she was just into it and her volume peaked every time.
Edit: It was painful to listen to, to be honest, and this is only because I could feel all the friction in her throat. As a singer myself I know what it feels like when that happens to my voice. It's painful!
If I could sing like this my life would be complete and my a**hole of friends wouldn't tell me to stop singing even when I'm literally whisper singing the songs
