When they click (''Over the Rainbow,'' ''Let It Go''), they're timeless; when they clunk (''The World Is Not Enough''), they're also unforgettable -- for the wrong reasons; see what struck a chord or fell flat for us
Céline Dion, ''My Heart Will Go On''
Why it struck a chord: Celine's here, there's nothing to fear! Partnered with the film that would become the most expensive, highest-grossing, most Oscar-winning film of all time, Dion's 1997 anthem was appropriately epic in its soaring melody as well as its through-the-roof sales ''My Heart Will Go On'' is, to date, the eighth-best-selling single of all time. An Irish pennywhistle has never packed so much power.
