history: I was listening to a playlist of music, and an old song that I hadn't heard since I was a kid. It instantly made me feel the exact feelings I had had when I was a young kid when I would listen to that song while spending time with my family.
current:  I was listening to this random music playlist on Youtube and then this song that I hadn't heard since I was a kid, that I had completely forgotten about, came on and brought back all these childhood memories.
next: What was the song?
