I would have been happy to vote for any and all of the tracks in the above thread (edit: see next toot), but I whittled my list down to these final four
@Langile great simple melody (#earworm), clear and lovely implied harmony, beautiful voice and singing, touching lyrics (even without tuna), what’s not to love ?
My earworms often get triggered by seeing or thinking an object, such as a street sign, or word. For example, whenever I eat a potato or think the word "soon", there's a good chance I will earworm the excellent อีกไม่ช้า (Soon), by Thai rock group Potato (featuring Slot Machine).
