DΕjin music, also called otokei dΕjin in Japan, is a sub-category of dΕjin activity. DΕjin are non-official self-published Japanese works which can be based on official products or completely original creations. DΕjin music isn't a musical genre in itself but is indicative of a particular publishing way, like the term "indie" would be.
DΕjin music consists very often of video game music fan arrangements. Much original music is also created, be it music for dΕjin games or simply mainstream music such as pop, rock, techno or trance.
By nature, dΕjin music is most often reduced to synthetic digital productions which allow for self-production at low costs, as opposed to studio mastering live instruments require. As much as full live instrumentations are rare though, it is pretty common to have one live instrument such as a guitar backed up by synthetic orchestrations.
