Shiina Mota's instrumentation and vocal tuning are unrivaled. And somehow, even when bright, there is always a underlying sense of gloom. The profound lyrics spat out through the voice of a machine feel as if they are singing of the human heart, making them seem somehow endearing and poignant. I cannot give this 5 stars because 'Young Girl A', the work that represents him, seems to trap him excessively in the image of a tragic genius. Around the time the experimental atmosphere in Vocaloid began to subside after 2013, his musical style also underwent many changes. That fact is vividly felt in the minimal composition and somewhat floating tuning of his posthumous work, 'Please Give Me a Red Pen', which seems conscious of mainstream appeal. What would it have been like if music criticism had existed earlier in Vocaloid?
