All the real artists are thieves?

Taking pride in original songwriting however begs the question, What is an original song, when it comes to folk music (or any genre)?

All aspects of creativity are basically reconstituted bits and pieces of things we’ve seen, heard and experienced, finely or not-so-finely chopped and served in a form that hopefully blends the ingredients into something “new.” The ancient Greeks seemed to know this, expressed in their belief that the Muses of creativity were the daughters of Mnemosyne, Titan goddess of memory. Perhaps we would like to think that the thoughts that go into creating a new song are purely impressions from “real life,” but a melody does not suggest itself as much from the impression of the 6 train ride you took this morning as it does from a melody from another song. The same for chord progressions, song concepts, lyric sounds and patterns, song structures and everything else. Folk music is supposed to be a shared continuum after all, and as Louie Armstrong said, “All music is folk music, I ain’t never heard no horse sing a song.”

Despite knowing all this, as a supposedly “creative” artist I am often shocked to discover that a song I’ve written has been a blatant unconscious rip-off of somebody else’s song, either in its structure, or lyrics, etc; if I’m lucky the other person’s song is not particularly popular or recognizable!
