Yes mine changes around too. At times I think it is “Silence Is Golden” by the Tremeloes.
Although I do not care for him personally, “Kodachrome” by Paul Simon has to be the swingingest song ever, well maybe with the exception of “Double Shot” by The Swinging Medallions”.
I also like “Kodachrome” and “Double Shot.” “Kodachrome” was playing on the car radio when I got home after completing four years of college.
