Celine Dion - "My Heart Will Go On"

There’s probably no one on the planet at this point who hasn’t heard Celine Dion's Titanic theme song. But if there was, they might almost think, on first listen, that the song was ending three minutes in. That is, until they heard the dramatic modulation that takes place around around 3:24. Takeaway: don’t try to stop Celine’s heart from going on prematurely.
