DATEKEN is a relatively well-known Vocaloid composer who submitted his first song onto niconico in October 2008, and prior to that he had experience in composing instrumental songs since 2005, which he uploaded onto his muzie account. DATEKEN’s most well-known song is 紡唄 -つむぎうた- (Tsumugi Uta/Spinning Song), which currently has over 11,000+ mylists and 190,000+ views. DATEKEN is actually a graduate student from Hokkaido and his hobbies include playing the piano, doing karate, and reciting poems.
DATEKEN uses only Kagamine Rin and Len to sing his songs, and at this point has not used any of the other Vocaloids yet. Each of his Vocaloid songs have a different genre assigned to them, ranging from ethnic (Jutenija), technopop (Ur-Style), R&B (イマジネイション/Imagination), and even waltz (schwarz waltz), which really show his high level of versatility as a composer. However, most of his songs generally belong to the electronic music genre, such as techno, trance, 2-step, and house. All his songs are extremely high quality, and give a really good representation of their respective genres. Song themes are really varied, which makes all of them impressionable and easy to remember, and the large majority of songs are quite catchy. His vocal tuning for the Kagamine twins are also impeccable, and in my opinion ranks among the best as they are consistently natural and easy to listen to. (Definitely not a small feat considering that Kagamine Rin and Len are among the harder Vocaloids to tune.) He also changes their voices according to the song, and as a result they always sound fitting and different. As a one-man composer, DATEKEN does everything himself: writes and arranges the song, writes the lyrics, and makes his own videos, which are usually well-subtitled and with a nice static layout and picture, the latter of which he borrows from royalty-free artists on Piapro.
In addition to composing Vocaloid songs, he has also composed intrumental tracks also to the theme of widely varying genres, and has also released a Touhou arrange doujin album called 当方暇軍団 under the circle name of 暇軍団. He creates songs with a keyboard controller for the most part.
All in all, super-good and incredible composer. Please listen to all his songs! I especially recommend his works if you want to explore different musical genres.
