Zell’s favorite song is K.K. Swing. You can score some major points with Zell by getting the K.K. Swing album and gifting it to him. Zell appears on the cover of K.K. Waltz, but this is not his preferred K.K. song. Zell does have a music hobby, so it is no surprise that he has inspired K.K. Slider on a few of his best songs!
