It's been so long since the release of "History" that it's easy to forget this iconic classic. EXO has dropped so many pivotal and memorable singles, it's easy for one to completely wipe the other out of our memory.

This ultra-repetitive ear-worm easily gets stuck in your head, but somehow got overshadowed by a number of TWICE's more successful songs. "I'm Gonna Be a Star" is a nice reminder and look into TWICE's humble beginnings. Sana, Mina, and Jihyo shine as vocalists on this particular song.

"N.O" is another track that's been overshadowed by its successors. BTS has so many iconic and vividly extravagant songs and comebacks, that it's easy to forget when the group was just starting out with this song. A harsh critique of society, this song was a huge statement at the time of its release. Little known fact- "N.O" stands for "No Offense".

SHINee's "Dream Girl" is a charming and super wholesome track that was released during SHINee's drop of their third studio album. When this song comes on, it's easy to get a wave of nostalgia washing over your entire body. Lots of K-Pop fans have very fond memories of this song.

Red Velvet is known for colorful and sassy comebacks, but "Be Natural" was much more toned down and mature in comparison. The girls of Red Velvet don fitted pantsuits in the music video and do extremely artistically-driven choreography, but fans often forget this elegance when thinking about all the extravagant and saturated concepts that they have done beyond this song.

We haven't heard too much from K.A.R.D. in about a month now that they've released a new MV. This song will forever be etched in our memories, however. "Don't Recall" has a simple concept with a wonderful execution.

Though "Be Mine" was originally made for Intel, this track actually went over extremely well with fans. Because it wasn't put on any official release, however, many fans didn't catch on to its release. Well, here's your chance!

A lot of us have listened to so much Girls' Generation that we've burnt out on some tracks. However, "Galaxy Supernova" is still a refreshing and palatable song that reminds us of K-Pop's golden era. A forgotten oldie, but goodie!

With Hyuna's recent 'scandals', fans have forgotten about the roots of her career with Wonder Girls and 4minute. It's nice to revisit a calmer time when 4minute came out with the New Year bop "Whatcha Doin' Today?".

This is G-Friend's most "out there" release. The song, "Fingertip," is vastly different from the group's other songs and concepts. Similarly to Red Velvet, it's easy to think of a group as their most commonly used concept they tend to convey, so it's very much the same case with G-Friend.
