緊隨Higher Brothers其他成員馬思唯, KnowKnow, Melo分別釋出個人專輯之後，壓軸出場的Psy.P今日釋出了全新單曲”King of the Jungle”，並宣布即將發布首張個人專輯《PSYLIFE.25》。作為新專輯的首發單曲，"King of the Jungle" 完美呈現了Psy.P辨識度極高的低沈嗓音和獨特的腔調，將巧妙的比喻和連貫的flow貫穿全曲。該單曲還邀請了好兄弟Melo的加盟，共同向歌迷描繪了一幅弱肉強食充滿競爭的殘酷世界畫卷，而自己如叢林之王般站在食物鏈最頂端傲視群雄，以此來比喻自己在說唱事業上一路打拼以來所獲得的成功。
Following the release of solo projects by other members of Higher Brothers, Masiwei, KnowKnow and Melo, Psy.P gears up for his new single & music video for "King of the Jungle" today, and announced that his very first solo album "PSYLIFE.25" is on the way. As the debut single of the new album, "King of the Jungle" perfectly presents Psy.P’s highly recognizable low-pitched voice and is full of ingenious metaphors and coherent flow. He also invited Higher Brothers member Melo to join, and together they paint a picture of a brutal, competitive world. In this world, they are standing at the top of the food chain like King of the jungle, as a metaphor for Psy.P's success in his rap career.
