Thrash metal is a subgenre of heavy metal music, one of the extreme metal subgenres that is characterised by the high speed and aggression.  Thrash songs typically use low-register guitar riffs, overlaid with shredding-style lead work. Thrash song lyrics express nihillistic views or deal with social issues using visceral, gory language, an approach which partially overlaps with the hardcore genre.

Viking metal is a term used in reference to heavy metal music with a dramatic emphasis on Norse Mythology, Norse Paganism, and the life and times of Northern and Central Europeans prior to the Christianization of Scandinavia. It is still debated whether or not Viking metal can be considered a stand alone "genre", or merely an ideological off-shoot of other genres, as the influence of style being played varies among artists.

Alternative metal is an eclectic form of music that gained popularity in the early 1990s alongside grunge. In many instances, it can be accurately described as a fusion of heavy metal and alternitave metal. It is characterized by some heavy metal trappings (most notably heavy riffs), but usually with a pronounced experimental edge, including unconventional lyrics, odd time signature, unusual technique, a resistance to conventional approaches to heavy music and an incorporation of a wide range of influences outside of the metal music scene.

Sludge/doom is mix between hardcore and doom metal. Sometimes called "doomcore", it's actually a doom metal with roots in hardcore instead of traditional heavy metal. Combining the slow riffing and depressive outlook of doom metal with the raw abrasiveness and shrieked vocals of hardcore, sludge is at some of the outer limits of doom metal, although a couple of bands such as Eyehategod and Crowbar are fairly well known within the metal community, especially in the New Orleans sludge scene from which they came. Even though first sludge bands sport the "booze 'n' bongs" image synonymous with stoner rock, they lacked the stoner rockers' positive outlook on life. Lyrical themes are typically centered around misery, hatred and nihilism, but also social and political issues owing to its hardcore roots. Some examples are Eyehategod, Grief, Anticlimax, Corrupted and Crowbar.
