I didn't know it, but Koronba did some amazing UTAU songs. I knew for so much long and love them so much, only to discover the sad situation Koronba seems to be right now. It is truly sad. But fortunately most of his works seems to have been saved. I know I already posted this on LCD DEM wiki, but I felt like people here could understand and relate to this situation too. Please check Koronba's music and this game's OST. You can find plenty of it both on YouTube and in the Uboa-chan's thread linked to this post.
