Seth Rudetsky did a thing about head vs. chest voice, and how it was odd to be listening to a song you'd expect to be in head, which was sung in chest, and vice versa.

And what was worse was expecting a song to be sung in either, and instead you get a dramatic monologue by Cher (doing I feel pretty)

Omg. I can't with this.

It's a lot to take in, yup.
