Since the genre's inception more than half a century ago, metal music has maintained its place as a major music genre and culture across the globe. With hundreds of thousands of bands spread across every continent, the genre has become a diverse canvas of continually changing translocal scenes. Serious scholarship covering metal music has been propagating across academic fields since the 90s with a wide variety of approaches, but quantitative studies of the genre almost always depict metal as a monolith; a singular uniform entity without internal variation. This research aims to illustrate how quantitative analysis of metal can accurately reflect the genre’s major content variations, first by constructing a dataset of the Encyclopaedia Metallum: The Metal Archive that reflects major subgenre and lyrical themes within metal, and then applying said dataset to understand how metals content shifts both between major subgenres and across geographic space.
