26. "Good Times," Chic
It might not seem like a seasonal tune at first, but this disco classic (which dominated the summer of 1979) is all about getting down on steamy nights "'bout a quarter to ten." (Its B-side was the luxuriant "On A Warm Summer Night".) According to Chic, the sporting life includes clams on the half shell and roller-skating. Who are we to argue with those who can create a groove as recognizable as the national anthem?
