“(Good Riddance) Time of Your Life” by Green Day
This Green Day hit has become the ballad for graduations everywhere. But did you ever wonder why ‘Good Riddance’ is in the title? Because Billy Joe Armstrong wrote the song about his frustration with a girlfriend who was moving to Ecuador and breaking up with him. “I wrote the song as kind of a bon voyage. I was trying not to be bitter, but I think it came out as a little bitter anyway,” he said.
