Curious after Guitarist: more songs to hear from D.O. (Doh Kyung-soo) right now

A track from ‘The Seasons: Sung Si-kyung's Eardrum Boyfriend’, released on October 15, 2026. D.O. sings anew a song composed by Sung Si-kyung, with lyrics by Shim Hyun-bo and this arrangement by Kwon Ji-yoon. Its meaning lies in meeting a familiar melody in a different voice rather than in a new self-written song. Listen to how the feeling of love comes through in an arrangement of piano, guitar and bass together. It opens this selection at a different pace from the lively DOPAMINE songs that follow.

The first track of the fourth mini album DOPAMINE sets off with a band sound led by drums and guitar. It’s about the feeling of running free and singing out loud, and it has passages made for singing together. For those who remember D.O. through calm ballads, it’s a starting point that shows the brighter side of his voice. It’s a separate song from ‘SING ALONG!’ on the 2025 studio album, so the two can be heard back to back. Here, focus on its role of opening up the album’s energy.

The second song on DOPAMINE is an up-tempo indie pop-rock dance track. Acoustic guitar carries the rhythm, with jazz chords, drums and bass added to create a mood that makes you want to move a little. It’s a pick that shows not every song with a guitar is a quiet one. The party in the title works just as well imagined as a drive with your body given over to the music rather than a big event. In ‘Guitarist’, which follows, the same instrument conveys emotion in a far more restrained way.

‘Guitarist’ offers a restrained rhythm grounded in R&B and soul. Here the guitar goes beyond accompaniment to become a device expressing the flutter between two people. PENOMECO, who also worked on ‘Fit’ and ‘DUMB’, took part in the lyrics, and D.O.’s vocals widen their range of expression toward the latter half. Its appeal comes into focus when you follow the space between the playing and the voice rather than big bursts of emotion. It’s the central track to recommend to anyone who wants to meet his recent music one song at a time.

‘Don’t You’ is an up-tempo pop-disco track anchored by funky guitar and bass and groovy drums. The key to listening is that it carries inspiration from 1970s funk into a modern sound. Placed after the restrained flow of ‘Guitarist’, it shows how the character of the rhythm changes even within the same album. If hearing the song makes you curious about the movement, continue on to the DAYOFF performance in the separately gathered list of official videos. It’s a good spot to enjoy the link between the recording and the stage.

‘Dear’ is a ballad that opens with gentle piano and is the last track on DOPAMINE. Past the dancing rhythms of the earlier songs, its center of gravity shifts toward a voice slowly building emotion. The structure is worth following as guitar and strings join in the latter half and the sound widens. It isn’t a song sung at one volume from start to finish, but one where you hear the feeling grow. If you’ve listened to the album in order, you need to pass through this final scene for the difference in temperature across the five songs to be complete.

A single released on September 16, 2025, featuring PENOMECO. PENOMECO later took part in the lyrics of ‘Guitarist’ as well, continuing his work with D.O. The roughly 2-minute-9-second track captures the meeting of the two artists. If you’ve grown used to D.O.’s voice first, now it’s time to hear the difference that arises when another artist joins in. Rather than stopping at the tracks of one album, it widens the listening to a collaboration single.
