The ninth compilation album from Japan's internationally acclaimed chill & relax media brand "Lonely Girl" has been released, with this single serving as its cut. The theme this time is "AM 1:30 / Sleepless Nights," and artwork by Tomoko Oshima depicting a girl standing by her bed, inspired by this theme, was unveiled beforehand. A lo-fi-leaning chill instrumental centered around softly diffused piano phrases. The phrases don't assert a clear melody too strongly; instead, slight fluctuations and reverberations layer like fragments of memory. A track that doesn't reject your thoughts but accepts them during those quiet moments of sleepless nights when you find yourself reminiscing about past events. The artwork was created by illustrator/manga artist Tomoko Oshima. Please enjoy a quiet, relaxing time through this work during those sleepless nights, when you feel alone in the dark.
