What about Thanksgiving music? Let's see "Alice's Restaurant" in 4 part harmony, or whatever it was, and maybe the "Turkey Trot" by Little Eva, I think. Easter fares just as well. "Here Comes Peter Cottontail", and maybe "Little Black Egg" which was originally intended as a twisted Easter tune. New Years, just one, "Auld Lang Syne". Oh wait, two, "New Years Day" by U2. There's a few with the 4th of July/Independence Day in the title or lyrics or about fireworks. And then anything and everything patriotic. Memorial Day - I don't recall anything special except patriotic tunes again. Labor Day - "Friday On My Mind", "Working For The Weekend", "9 to 5", "Take This Job and Shove It", and all the old union hymns, but the radio doesn't play those, LOL. But there is at least a couple hundred that were either written about or for Halloween, or would just fit in. I think if a radio station was adventurous enough and played some outside their genre, they could go Halloween for a week. But Christmas is of course the big winner. Really only maybe 100 or so core songs each covered by multiple artists.
