SM Entertainment Artists on Kpopless — A Sound Guide

SM's founding era acts are the hardest to identify for most players because the production sounds genuinely dated — late-1990s Korean pop production with thin synths and drum machines that don't resemble anything contemporary. H.O.T were a boy group that dominated Korean charts in the late 1990s; S.E.S were their girl group equivalent. Shinhwa are notable for being the only 1st gen SM group that never disbanded — they're still active in some form decades later.

For Kpopless specifically: if you hear something that sounds like it could be from a late-1990s Western pop CD but with Korean lyrics, and the production is noticeably thinner than anything post-2003, you're almost certainly hearing a 1st gen SM track. H.O.T had a particular style of synth-heavy, rapid-fire rap intro that became a template for the era.

SM's 2nd generation roster is their most diverse and arguably their most beloved by longtime fans. TVXQ (also known as DBSK) were a five-member group that became one of the biggest acts in Asia before a member split in 2010 reduced them to a duo. Super Junior were a 13-member boy group whose catalogue spans disco-pop, ballads, and EDM. Girls' Generation (SNSD) are one of the most iconic girl groups in K-pop history — their bright, choreography-focused pop was the template for modern girl group performance.

SHINee deserve particular attention on Kpopless. They're one of the groups most frequently identified correctly by era but guessed wrong by song — their production style is distinctively consistent, with a particular quality of synthesised sound and Jonghyun's voice that players often recognise immediately. The problem is that SHINee has deep catalogue depth and many of their album cuts sound similar enough to each other that without very specific familiarity, you'll know it's SHINee but not which song.

f(x) are SM's most experimental act of any generation. Their music drew from art-pop, nu-disco, electropop, and IDM in ways that didn't fit the standard K-pop formula. "Electric Shock," "Nu ABO," and especially the Pink Tape and 4 Walls albums contain some of the most unusual production in the SM catalogue.

EXO debuted in 2012 and immediately became SM's flagship 3rd gen group. Their sound spans from the theatrical R&B of "MAMA" and "Overdose" to the more accessible pop of "Ko Ko Bop" and "Power." EXO's discography is wide enough that placing a specific B-side requires real familiarity with their full catalogue — but their title tracks are among the most recognisable in 3rd gen K-pop.

Red Velvet are SM's 3rd gen girl group and are famous for their dual concept: "Red" (uptempo pop) and "Velvet" (sophisticated R&B). Seulgi's alto and Wendy's soprano make them vocally distinctive, but the challenge on Kpopless is that Red Velvet's Velvet-side tracks can blend into a broader "SM girl group ballad" category if you're not careful — Joy's voice in particular can sometimes be confused with SNSD members by players who know both groups only loosely.

NCT (and its various subunits) are SM's most experimental 3rd/4th gen project. The idea was an "infinite" group with rotating subunit members — NCT 127 (Seoul-based unit), NCT Dream (younger member unit), and WayV (Mandarin-language unit). NCT's production is more aggressive and genre-blending than other SM acts, particularly in tracks like "Kick It," "The 7th Sense," and "Regular."

aespa are SM's primary 4th gen girl group and represent a significant departure from the Red Velvet template. Their concept — four members with AI avatar counterparts living in a virtual world — is embedded in the music itself: their songs often feature layered, electronic sound design that references this virtual-physical divide. "Black Mamba," "Next Level," "Savage," and "Spicy" are all radically different sounds, which makes aespa tracks interesting on Kpopless. You might hear something and recognise it as contemporary SM without being able to immediately classify it as any of their other current groups.
