[long piano and guitar intro begins]
That's odd. I don't recognize this song at all.
[Leon Russell starts singing]
Oh, "Prince of Peace." Cool. I haven't heard this in forever.
[fourth measure into the verse]
Crap. That part of the melody is very similar to something I just started writing. Crap.

It's salvageable. The vibe of "Prince of Peace" is very different from New Song, and I should be able to change up my melody enough that I don't get into trouble. Doing so means one more thing to think about, though, and I'm having enough trouble getting New Song off the ground.
I realize this happens to songwriters all the time. Still annoying.
