Bytebeat is a minimalist form of algorithmic music in which very short computer programs (often a single arithmetic expression) generate raw PCM audio directly. It typically uses 8-bit integer math and a running time counter t to produce harsh, glitchy, melody-like patterns, rhythms, and textures through bitwise operations, shifts, modular arithmetic, and simple integer multiplications. The aesthetic sits between chiptune timbres and noise art: crunchy aliasing, stepping waveforms, and emergent structure arise from extremely compact code. First popularized online in 2011, bytebeat is as much a programming puzzle as it is a musical style, celebrated for revealing how complex musical behaviors can emerge from ultra-simple rules.

Glam metal (often called hair metal) is a flamboyant strain of 1980s hard rock and heavy metal defined by high-energy riffs, anthemic choruses, and glossy, radio-ready production. It pairs the swagger of hard rock with pop hooks, multi-tracked vocal harmonies, and virtuosic guitar solos. Visually, the style is theatrical: teased hair, makeup, spandex, and flashy stagewear echo the glam rock of the 1970s, while the music embraces both party-ready anthems and power ballads. The sound is big, bright, and built for arenas and MTV-era music television.

Speed metal is a fast, precision-driven branch of heavy metal that crystallized at the turn of the 1980s. It emphasizes aggressive tempos, tightly synchronized riffing, and virtuosic lead guitar work, while generally retaining melodic, often clean or strident vocals. Compared with thrash metal, speed metal tends to be less percussive and more melodic, favoring galloping rhythms, twin-guitar harmonies, and classic verse–chorus structures. Drums often employ rapid double-time feels and double-bass patterns, while bass frequently mirrors the rhythm guitar to reinforce propulsion. Lyrical themes range from rebellion and street realism to fantasy, warfare, and sci‑fi.

A flamboyant and hedonistic subgenre of heavy metal and hard rock that exploded in the early 1980s, centered specifically around the nightclubs of the Sunset Strip in West Hollywood, California. Characterized by a distinct visual aesthetic involving teasing hair, make-up, spandex, and leather, the sound fuses the rebellious attitude of punk, the catchy hooks of pop, and the guitar virtuosity of heavy metal. Lyrically, it celebrates excess, focusing on themes of sex, drugs, partying, and romance, often alternating between high-energy anthems and sentimental power ballads.

Thrash metal is an extreme subgenre of heavy metal defined by blistering tempos, tightly palm‑muted low‑register riffs, and sharp, aggressive execution. Songs commonly drive at 180–240 BPM, pairing chugging, down‑picked rhythms with shredding leads and rapid alternate‑picked lines. Drumming emphasizes double‑kick work, skank/D‑beat patterns, and abrupt, syncopated accents that lock tightly with the guitars. Vocals range from rough, shouted delivery to snarling barks and occasionally cleaner, declamatory phrasing. Lyrically, thrash favors social critique, anti‑authoritarian themes, war and dystopia, and street‑level realism, matching the music’s urgency. The overall aesthetic is lean, fast, and technical—channeling the speed and directness of hardcore punk through the tonal weight and precision of heavy metal.

US power metal is an American take on traditional heavy metal that fuses the galloping drive of the NWOBHM with tighter, more aggressive riffing and a darker, grittier edge. It favors heavily distorted, palm‑muted guitars, muscular mid‑to‑fast tempos, and commanding, theatrical high‑range vocals that often soar above twin‑guitar harmonies. Compared with its more keyboard‑forward European counterpart, US power metal is typically guitar‑centric and rhythmically harder, sometimes borrowing speed/thrash accents while keeping a melodically heroic core. Lyrics commonly explore fantasy, mythology, warfare, history, and epic personal struggle, delivered with a dramatic flair and chorus hooks designed for crowd shouts. Arrangements often feature modal minor harmony (Aeolian/Phrygian, harmonic minor), call‑and‑response leads, and tightly composed bridges that build to climactic codas, all captured with punchy, relatively dry production that emphasizes riff definition and vocal power.
