cosMo@Bousou-P (cosMo@暴走P), also known as Kuroneko Antique (黒猫アンティーク), is a composer. He is known for creating incredibly high-speed songs with the tempo that exceed 200 beats per minute, and is most popular for his "Infinity" series and his "Bousou" series. Most of the lyrics appearing in the series are strange stories known as denpa song (addictive songs with weird and incoherent lyrics) in Japan. He has received the "High-Speed Development Miku Master" title on NicoNico Video.
Cosmo is certainly not one of the worst Hatsune Miku producers of all time--far from it, actually. However, he is one I certainly skip a lot whenever his songs come up in my randomized playlists. As mentioned above, his songs are known for exceeding 200 beats per minute. With the already robotic and high-pitched voice bank of Miku paired with the high speed BPM, the songs end up being very ear-scratchy, pitchy, and unable to overall bum along to. Thus, I rank him as one of my least favorite artists that I have come across.
