Ooooh this is an easy one. My all time favorite has to be "Stand By Me" by Ben E. King. I was in the 6th grade and this was 50 years ago and I managed to save up a whole dollar and then walked to the corner record store. It was owned by a woman that I so admired because...well, she had her own business! I bought it, raced home and played it for hours on the phonograph. Knew every word too. I have lots of favorites songs but this one stands out so much because of all the events around it.
