마음의 숲

마음의 숲 ("Forest of the Heart") is a song by the Korean YouTube channel Joseon Hiphop, made with the AI music generator Suno for both its music and its vocals, according to the Korea Herald. The channel posted it on YouTube on 9 April 2026 with a description presenting it as a place to rest at the end of an exhausting day and a word of comfort for people who have worked hard, tagged as AI music with an AI-made music video; it went out on Spotify as a single in May. On 6 September 2026 it became the first AI-generated track to enter Melon's Top 100, dropping out again on 8 September. The creator told local media that listeners respond to lyrics that tell them it is fine to rest rather than telling them what to do, and the channel said a remake sung by a human singer was being prepared. By late September the YouTube upload had passed 5.4 million views.
