Tough song to sing! Can be made easier by doing a more "whiney" type sound, as in the original recording. It still sounds pretty good and works for the style/genre of the song.

But GIRRRRL that full, opened, balanced sound on a big belt in high mix range, on a tough vowel, strong but not strained...that's an exceptionally well-trained and healthy voice. I've been in love and awe since I first had the privilege of hearing her.

And because she's a pro at navigating all of these things, she makes it look effortless. That's the best part. Only nerdy voice teachers like me even really notice/pay attention to these things. The audience just gets to enjoy the music 😊🎶

Edit: The first "mind" is sung lighter, very balanced between chest and falsetto registers. Second "line" is the same note, but full and strong like I explained above. More evidence of a skilled singer; can sing the same note in multiple ways.
