D.O. has returned with DOPAMINE, a five-track mini album led by “Guitarist,” adding a new release to the EXO vocalist’s solo catalog.
The album arrived September 8 at 6 p.m. KST through Blitzway Music. It is his fourth solo mini album, following Empathy, Expectation and Blossom.
The running order opens with “Sing It Loud,” followed by “Dancing Party” and the title track, “Guitarist.” “Don’t You” appears fourth, with “Dear” closing the release. The sequence is listed in Kprofiles’ album guide.
That guide lists collaborators including AJ Mitchell, Anthony Watts, Violet Skies and Ryan Lawrie among the album’s composers. It also includes D.O. in the composition credits. The listing brings together contributors working across the project, rather than identifying every songwriter with every track.
“Guitarist” serves as the focus of the promotional campaign. D.O.’s official account highlighted the song on release day, and its music video is available on YouTube. The rollout also included concept films titled “Daily Dopamine” and “Missing Guitar,” along with a highlight medley and video teasers.
The mini album follows Bliss, his first full-length solo album, released in July 2025. That record contained 10 tracks and was led by “Sing Along!” The shorter DOPAMINE returns him to the EP format while continuing the recording career he maintains alongside EXO.
D.O., also known as Doh Kyung-soo, began releasing solo EPs with Empathy in 2021. Expectation followed in 2023, and Blossom arrived in 2024 with “Popcorn” and “Mars.”
For listeners approaching the new release through its music video, “Guitarist” is the starting point. The complete five-song sequence places it between two opening tracks and the closing pair of “Don’t You” and “Dear,” giving fans the broader project beyond its promoted single.
