7. Celine Dion, 'My Heart Will Go On'
Not everyone will admit it now, but back in 1997 most everybody thought Titanic was a great movie. (It even won Best Picture!) The soundtrack also sold about 10 trillion copies, entirely based on the astounding success of the single "My Heart Will Go On." Celine Dion's song and the movie have aged very poorly, but if you were a 13-year-old girl in 1997 odds are very high this song made you cry your eyes out. Now it probably just makes you cringe.
