Previa is a contemporary Argentine pre‑party DJ style built around high‑energy edits, bootlegs, and mashups designed to kick off the night. The name comes from the colloquial “la previa,” the pregame gathering before going out, and the music’s job is to turn familiar Latin pop, reggaeton, and regional hits into floor‑ready, faster, harder versions. Sonically, previa lives between tech‑house tempo and reggaeton sensibilities: hooks are sped up, drops hit with big sidechained bass, and builds are short and dramatic. DJs chop sing‑along choruses, stack hypechants and FX, and slam dembow or four‑on‑the‑floor kick patterns under recognizable vocals. The vibe is extroverted, party‑starting, and unapologetically functional—made for mass sing‑backs and immediate dancing.

Merseybeat is a British beat style that emerged in early-1960s Liverpool and the surrounding Merseyside area. It blends the exuberance of American rock and roll and rhythm and blues with the skiffle-derived DIY energy that swept Britain in the late 1950s. Hallmarks include tight vocal harmonies, short and catchy verse–chorus forms, a strong backbeat in 4/4, melodic walking or bouncing bass lines, bright rhythm guitars (often with a jangly timbre), handclaps or tambourine accents, and lyrics focused on youthful romance and everyday optimism. The sound is guitar-bass-drums–centric, hook-forward, and danceable, laying the foundation for the British Invasion and shaping subsequent pop and rock craft.

Pop rock blends the hook-focused immediacy of pop with the instrumentation and drive of rock. It prioritizes catchy melodies, concise song structures, and polished production while retaining guitars, bass, and drums as core elements. Typical pop rock tracks use verse–pre-chorus–chorus forms, strong vocal harmonies, and memorable riffs. The sound ranges from jangly and bright to mildly overdriven and arena-ready, aiming for radio-friendly appeal without abandoning rock’s rhythmic punch.

Beat music (often called Merseybeat when centered on Liverpool) is a British style of early-to-mid 1960s guitar pop built on a strong, danceable backbeat, close vocal harmonies, and concise, hook-driven songwriting. It blends the rhythmic drive of American rock and roll and rhythm and blues with skiffle’s DIY energy and doo‑wop’s harmonies, typically delivered by two electric guitars, electric bass, and drums, with frequent handclaps and tambourine. Songs are short, catchy, and youthful in theme, favoring major keys, I–IV–V progressions, and memorable choruses that foreground melody over instrumental virtuosity.

Pop is a broad, hook-driven style of popular music designed for wide appeal. It emphasizes memorable melodies, concise song structures, polished vocals, and production intended for radio, charts, and mass media. While pop continually absorbs elements from other styles, its core remains singable choruses, accessible harmonies, and rhythmic clarity. Typical forms include verse–pre-chorus–chorus, frequent use of bridges and middle-eights, and ear-catching intros and outros. Pop is not defined by a single instrumentation. It flexibly incorporates acoustic and electric instruments, drum machines, synthesizers, and increasingly digital production techniques, always in service of the song and the hook.

Rock and roll is a high-energy, dance-oriented popular music style that emerged in the United States in the early-to-mid 1950s. It fuses the 12‑bar blues and boogie‑woogie with the backbeat and instrumentation of rhythm & blues, the twang and storytelling of country, and the fervor of gospel. Its hallmark sound centers on a strong backbeat (accented on beats 2 and 4), driving rhythm sections, electric guitar riffs, prominent piano or saxophone leads, and catchy, chorus-forward songwriting. Typical harmonies revolve around I–IV–V progressions, often in 12-bar form, with swung or shuffle feels and punchy turnarounds. Culturally, rock and roll catalyzed a youth movement linked to dancing, teen identity, and social change. It bridged racial audiences by popularizing Black American musical traditions for mainstream listeners, and it laid the foundation for subsequent rock styles and much of modern pop.
