BTS’s Jin said his fans’ support “has left a lasting resonance in my heart,” like the title of his latest EP “Echo.”

Echo follows the November release of JIN’s debut solo EP Happy, which reached No. 4 on the Billboard 200. The project featured single “Running Wild,” which marked JIN’s second Billboard Hot 100 entry separate from his mega-famous boy band, following 2022’s “The Astronaut”; the two tracks reached Nos. 53 and 51 on the chart, respectively.

Jin of BTS released his second solo EP Echo on Friday, unveiling seven new tracks that explore a range of emotions and life moments under the central theme of resonance.
