If you know one or more of these songs, consider yourself a true stan.

Arguably the origin story for K-Pop bubblegum pop, H.O.T's "Candy" is one of those hits that mobilized a generation of teenager superfans. The group's colorful, oversize outfits and giant mittens in this music video was an iconic pairing that established their classic '90s style. 

H.O.T. was for the masses, but g.o.d was what your cool cousins from Seoul actually listened to. This song (like any ode to mothers) gets me in the feels every time.

I dare you to get through this music video without sobbing. The group might not have reached fame beyond their early days, but this song earned a permanent place in every millennial teen's heart through its brilliant mash-up of K-Drama dramatics with K-Pop melodies. 

Sure, Rain was a great vocalist, but his promiscuous dancing is what brought him fame. Back in the 2000s, this song garnered special notoriety for the artist's illicit references to his "shaking magic stick." 😳

You can't talk about K-Pop girl group pioneers without mentioning S.E.S. This song was an absolute anthem and established S.E.S' sweet "girl next door" persona. 

Shinhwa did for K-Pop what N'SYNC did for American pop. This song stands out as one of the most classic and enduring boy group songs of K-Pop's first generation. 

Weirdly enough, it's possible that BoA ultimately achieved as much — if not more — fame in Japan than in South Korea. Nonetheless, she's still considered one of the original Queens of K-Pop, having cemented her status with this catchy, dancey tune that BoA released at the tender age of 15 (!).

Fin.K.L. launched Lee Hyori's career, but more importantly, it gave us "To My Boyfriend," and launched the group's "schoolgirl" aesthetic. You're welcome, Britney!

It's been nearly two decades since this song was released, but "Tell me tell me t-t-t-tell me" still rings in my ears like it was yesterday.

While Baby V.O.X was known as one of the first "bad girl" K-Pop girl groups to be formed, this track's heartfelt vibe captures the group's melodic range.

Known as the "Techno Queen of Korea," Lee Jung-Hyun shook things up in the K-Pop world by infusing the genre with techno energy. Her futuristic, edgy sound was one of those "hate it or love it" moments in K-Pop.

We can't talk about old school K-Pop without mentioning Seo Taiji and Boys. The group experimented with western sounds, especially rap, paving the way for the modern face of K-Pop.

Led by Teddy Park, 1TYM brought hip-hop to the idol world. Following his success, he used his talents to produce the sounds of major groups like BIGBANG and BLACKPINK. His hit-making talents are obvious in this earworm!

Clazziquai introduced nuance to the genre with a mellow, loungey tune that all the popular kids set as their Cyworld (like a Korean MySpace) background music. Later, the group regained even more popularity after doing the theme song for the K-Drama My Lovely Samsoon.

Projecting a softer and younger image than H.O.T, Sechs Kies is credited with establishing enduring elements of fandom culture, including specific colors and idol-specific merch. The fandoms escalated to a point where "fan battles" between H.O.T and Sechs Kies fans allegedly ended in fistfights. 

The song that ended Lee Hyori's innocent girl group affiliation (cultivated with Fin.K.L) and launched her sexier era. It also debuted her "brand," popularizing the iconic Y2K looks that honestly would probably trend today.

This is one of the early tracks that taught the industry the importance of a strong refrain. Today, "Run To You" still goes hard as a karaoke classic thanks to the song's irresistible "Bounce, bounce, bounce!" chorus.

Every woman growing up in '90s Korea remembers when this song came out in 2000. Describing a young woman's coming-of-age from innocent adolescence to a sensual, mature womanhood, the song shook up conservative society and enveloped the artist in controversy. Today, it's a go-to song for any idol wanting to drum up a bit of shock and surprise.

Debuting during the mid-2000s slump — a gap created by the disbandment of S.E.S and H.O.T — TVXQ! and their hit, "Hug," did more than reignite the K-Pop fanbase. The group's strong vocals proved that idols were more than just pretty faces and that they could actually sing. 

Kangta (formerly of H.O.T)'s solo career bridged the divide between K-Pop and R&B. In addition to the song's more soulful, mature vibe, the album itself featured Kangta with a bare upper body, raising quite a few eyebrows. (Oh, how our standards for scandal have changed!)

Make this throwback your summer anthem. There's nothing that screams peak Y2K K-Pop than this bop featuring Hwanhee and Brian's open shirts and biceps.
