Maybe not endlessly, but every day while cooking, for about two months, I hum the theme song from the old French movie "Un Homme et une Femme" (A Man and a Woman). When I know I'm going overboard I try humming "The Rose", originally sung by Bette Midler. When I think that's too often, I ask for a medley mix of other songs on my Google Nest Hub Max, but I keep going back to the two. Especially the French song.
