Woulda, Coulda, Shoulda Been A One Hit Wonder

I hate that I rarely remember my dreams. However, last night I had a rather vivid dream that I had written a song, and, if I do say so myself, it was quite good. It was a song about growing up.It had a catchy, walking piano part, a bit like in a Randy Newman song but slightly more complicated milf.The song's bridge was very sweet and melancholy-funny, and you couldn't help but sing along.But as soon as I opened my eyes, it slipped from my memory like smoke into wind. All I was able to hold onto was this lyric:
"When I was a young boyI had a young boy smile."I am very upset that I have forgotten the rest.
