That sounds like so much fun. Instantly i thought of the Beatles, so many of their songs are visual. Blackbird could be fun, the first line is pretty recognizable and easy to see. "Blackbird singing in the dead of night Take these broken wings and learn to fly"
I bet i would pick a song no one would understand or figure out, i'm usually a bit "out there"
Turn on the radio and close your eyes. I bet you find something that's in a song you enjoy and that would probably make the project even more fun for you.
