Kous is a very prolific Vocaloid producer, having uploaded more than 30 songs to Nico Nico Douga. He started uploading songs in 2008 and is still very much active. Because of his uploading speed, listeners gave him the epithet "shoukan kous" (weekly kous). His first pen name was actually "kou". However, due to multiple people with the same name, he decided to change his name to "kous" to make it more distinct. Kous's music seems to be within boundaries of many genres. Read more on Last.fm
