There are a lot of band names that are dumber than Metallica, but most of them aren’t worse. Hoobastank is worse, sure, but what makes Metallica such a bad band name is the smugness. It thinks it’s an amazing band name. When Metallica chose “Metallica”, they thought “This is the final word in metal. With this band name, we’ll be the heaviest.” And they wouldn’t have taken it if they didn’t think they were an amazing band. As far as I know, there isn’t an Indium or a Calypsomnibus or a Salsalmanac.
