"Always" hands the microphone to Yoon Mi Rae (Tasha Reid)—a vocalist whose tone can feel both intimate and stadium-sized. In Descendants of the Sun, where duty, distance, and devotion collide, the song works like a promise wrapped in melody: love that doesn't flinch when life gets loud.

Musically, it leans into sweeping ballad territory—big chorus, emotional lift, and a sense of steadiness that matches Captain Yoo Si-jin and Dr. Kang Mo-yeon's push-and-pull romance. Years after the drama aired, fans still return to the MV for that mix of nostalgia and catharsis—one reason the track remains a streaming heavyweight.

"Sweet Night" is a rare case where an OST feels almost like a private diary entry set to music. Performed and co-written by BTS's V, the track is sung entirely in English—soft indie-pop with guitar and strings that stay out of the way so his lower register can carry the emotion.

In Itaewon Class, the story is about grit, revenge, and healing; "Sweet Night" answers that with quiet empathy—like a wish for peace after a long fight. It's wistful without being melodramatic, which helps explain why the song traveled far beyond drama fans and became a playlist staple worldwide.

"For You" unites Chen, Baekhyun, and Xiumin—the voices that would later define EXO-CBX—for one of the most replayed ballads from Moon Lovers: Scarlet Heart Ryeo. The drama's palace politics and time-travel heartbreak needed a song that could sound tender without feeling fragile, and this OST delivers exactly that: layered harmonies and a melody that climbs like hope fighting against fate.

Lyrically, it reads like a letter written in the middle of longing—memories kept alive, promises whispered into uncertainty. On charts, it made a serious impact too (including strong showings on Gaon and Billboard's world rankings at the time), but its real legacy is emotional: if you watched Hae-soo's story, this track probably still gives you chills.

Gaho's "Start Over" (often listed as "Start") is the adrenaline shot in Itaewon Class's soundtrack—where Park Seo-joon's Park Sae-ro-yi refuses to stay down. The arrangement blends rock drive with an anthemic chorus, built for montages of walking through rain, rebuilding a life, and proving people wrong.

It became one of the defining K-drama OST breakthroughs of the 2020s: a song that feels like motivation turned into music. If "Sweet Night" is the bruise, "Start Over" is the decision to stand up again—and that energy is a big reason fans keep returning to the MV years later.

Crush's "Beautiful" is the kind of OST that doesn't need a fight scene to feel epic—just a piano, a voice, and the ache of loving someone you might lose. In Guardian: The Lonely and Great God (Goblin), the song attaches itself to some of the drama's softest, most cinematic moments, where fantasy romance meets very human loneliness.

It's soft R&B with a devotional mood: listening feels like standing in the snow, hoping fate will be kind. Fans still associate it with iconic scenes and "quote-tweet" levels of nostalgia—exactly the sort of timeless pull you see in long-form music features that celebrate K-drama soundtracks.

K.Will's "Talk Love" is Descendants of the Sun in a brighter key—pop and R&B stitched together with acoustic guitar, a sweet melodic lift, and that unmistakable whistling hook that instantly teleports you back to 2016.

Where some OST tracks stay tear-soaked, "Talk Love" chases the fluttery side of romance: the grin before a confession, the spark of a first meeting, the feeling that the world got louder in a good way. It's a classic "fan favorite" type of song—easy to hum, hard to forget, and perfect for rewatches.

Davichi built their name on emotional ballads that hit like a confession, and "This Love" is one of their most drama-perfect examples. In Descendants of the Sun, the track lines up with love that's tested by duty, time, and fear—so the vocals do heavy lifting: tender verses, soaring chorus, and that signature Davichi blend of power and fragility.

It's bittersweet in the best way—romantic, cinematic, and ideal for late-night listening when you want your feelings amplified. That combination is a huge part of why the MV continues to rack up views alongside the drama's global fandom.

"Everytime" pairs EXO's Chen with Punch—a collaboration that feels almost unfair to other love songs because the chemistry is that strong. It arrives early in Descendants of the Sun's emotional arc, when sparks are flying and every glance feels like a storyline.

Melodically, it's clean and addictive: romantic tension translated into pop ballad form, with a chorus that fans can recognize from the first second. Punch's vocal runs and Chen's tone create a duet that sounds like two people leaning toward the same future—one reason it remains among the most replayed K-drama OSTs on YouTube.

"Say Yes" is where softness meets swagger: Punch carries the romantic melody while Loco adds rap verses that feel like confidence wrapped in warmth. For Moon Lovers: Scarlet Heart Ryeo, that balance matters—the story is tragic, youthful, and intense, and the OST needed a track that could sound modern without breaking the historical mood.

The result is a song that fans describe as both "healing" and "addictive": a hip-hop ballad hybrid with a chorus that begs to be sung along to. It's the kind of entry that shows how flexible K-drama OSTs became—mixing genres while still serving the scene.

If K-drama OSTs had a hall of fame, "Stay With Me" would be engraved near the top. Performed by EXO's Chanyeol and Punch, the song pairs a dreamy, wintery instrumental with a vocal-rap interplay that feels cinematic from the first bar—perfect for Guardian: The Lonely and Great God's fantasy romance.

The MV became a phenomenon in its own right: a slow-burn ballad that somehow feels both intimate and enormous, the kind of track strangers recognize from the opening notes alone. Chart success aside, its real power is cultural—years later, it still represents "that one Goblin song" for millions of viewers worldwide.
