What is the best original motion picture song (with lyrics) of all time?

In my opinion, it has to be My Heart Will Go On (1997) as it not only topped the charts in more than 20 countries, but went on to sell over 18 million copies, iis the second best-selling physical single by a woman in music history, and one of the best-selling physical singles of all time.

Not only was it a good song, but served a duel purpose as a sort of memorial or homage to the 1500 victims of the real life tragedy.

Number 2, in my book, would probably be “Somewhere Over the Rainbow” which has passed the test of time.

What are some other great ones you think should be considered for best of all time?

For reference here is a list to the Academy nominees and winners in that category.
