About the theme

Rock Genres covers what you'd expect — grunge, metal, punk, indie, gothic — alongside the long compound names that mark the format: glamrock, psychedelic, alternative, classicrock, postrock, shoegaze, britpop, madchester. The long entries anchor the harder grids; the short ones (punk, indie, emo, doom) are easier. A theme for the people who care which decade the bass line came from.
