Whether it’s performed by the Modal Nodes or not, everybody loves that good tune from the Mos Eisley cantina in Star Wars—which true nerds will know is titled “Mad About Me.” It’s bouncy, it’s catchy, and it can easily be looped in such a way that it’ll just go on forever—the true mark of a good song.
