I don't knwo if you guys ever think about like the actual harmonies of her music, but if you really listen, she has like..killer vocals.
In Hands On Me you can hear her harmonies so clear. Like On the first chorus there's just a middle harmony along with her regular vocals.
Then on the second chorus, you can her her regular singing, her middle harmony, and the highest one.
It's amazing when you really listen to a song, you can really tell all of the work that goes into it.
