I enjoyed the favorite songs thread, but there are just too many to list. Here are two songs that aren’t favorites, but I cannot hear them now without these memories coming to me:
Reunited - this song came out right after my first girlfriend and I got back together after a long breakup. Whenever I hear this song I think of her.
Cecilia - when this song was popular there was a particularly mean nun - Sister Cecilia - at our school. We made up our own words for the song (can’t remember them), and when I hear it now it reminds of her.
