"Bon Jovi did it in "Livin' on a Prayer," Michael Jackson in "Man in the Mirror," and Celine Dion in "My Heart Will Go On." Taking a verse or a chorus up a notch by modulating the key was a way for pop stars to give their songs extra oomph for decades. We loved it because it made us feel things. And some of us are realizing just how much we miss the chills and thrills those modulations gave us."
