I'm going to start compiling a list of songs in search of the Greatest American Song of all freaking time (233 years). The basic criteria is that the person that wrote the song is/was a native born American and not someone who became a citizen later on. The song does not need to be patriotic, although Americans do tend to get overtly sentimental when paying homage to our country through song.
This is an open call to everyone and anyone to submit specific songs they would like to have considered for the Greatest American Song of all 233 years that America has been around.
If I had to pick one today, it'd probably be a Bruce Springsteen song, but I don't want to name it lest it influence submissions.
