Kenichi Maeyamada (前山田 健一 Maeyamada Ken'ichi?, born July 4, 1980), also known as Hyadain (ヒャダイン?), is a Japanese composer, lyricist, and musician. His primary work is composing anime theme songs and for J-pop musicians. He contracts through SUPALOVE, a Japanese record label. He has released a number of anime and video game music remixes, as well as original songs. These remixes have received over 20 million hits on YouTube and Nico Nico Douga.

Musical Style

Maeyamada began playing the piano at age four and first composed with a synthesizer in middle school. After graduating from Kyoto University, he apprenticed under lyricist Gorō Matsui. He got his first big break in 2007 for writing the lyrics to "Don't Go Baby", a song featured in Initial D Fourth Stage. In December 2007, he posted his first work under the name "Hyadain" on Nico Nico Douga, a remix of Crash Man's theme from Mega Man 2 with added lyrics. He initially struggled with criticism and accusations regarding these remixes' faithfulness to the source material. However, his videos gradually gained in popularity, particularly "Four Fiends of the Elements" from Final Fantasy IV and "Western Show" from Super Mario World. In May 2010, Maeyamada revealed that Hyadain was his pseudonym.

Maeyamada cites Yasuharu Konishi of the Pizzicato Five as a major musical influence, as well as Shoichiro Hirata and Yusuke Itagaki. Influence on his video game music stems from Nobuo Uematsu (Final Fantasy), Koichi Sugiyama (Dragon Quest), and Kenji Ito (Romancing SaGa). Lyrically, both his original works and fanworks are reputed for utilizing strong elements of humor and nostalgia. For his own songs, he provides all the voices, male and female, with the help of a digital voice modifier. These voices, Hyadain and Hyadaruko, appear as characters on his blog and in the music videos for "Hyadain no Kakakata Kataomoi-C" and "Hyadain no Joujou Yuujou".

Involvement in Nichijou

  1. Write, compose and sing Nichijou's first Intro theme song (both male and female parts).
  2. Write and compose Nichijou's first Outro theme song.
  3. Write, compose and sing Nichijou's second Intro theme song.
  4. Write and compose all 10 characters image songs + WEB Radio Single.
  5. Write, compose and sing in Nichijou no Remix Single.
  6. Involves in compositions for all 13 Nichijou BGM & Radio Bangumi albums.

In short, Nichijou no Gasshou Kyoku is the only single/album where he didn't have much roles. It's dumbfounding how a single season anime can produces so many singles/albums. Even more so considering single man is behind (almost) all of them. And with that many, where's the insert song: Headlight Taillight?
