Fan music: It refers to the creation, editing, publishing, circulation, and sale of musical works all under the management of the author. The understanding of "management" here is difficult, but the basic meaning is something like "being able to implement one's own will at all times."

Fan music is music products produced by amateur or professional individuals or fan associations, such as song records and song audio and video files, which are products of fan culture. It is mainly disclosed and sold at doujinshi sales events or related stores.

Doujin refers to "self-created, self-created without commercial influence", or "independent" creation. It has a greater degree of creative freedom than commercial creation, and the flavor of "creating whatever you want to create". Extended information

The scope of reference of fan music and fan words overlap. Generally speaking, works that focus on lyrics are called fanci, and the songs can use original music or any of the above types of fan music. Works called fan music focus on its arrangement or composition. However, when the term fan music is used in a broad sense, it often also includes works written by fans.

In addition, fan music and fan games are closely related, and there are often collaborative activities in providing music for fan games or creating original soundtracks.

Although the activities of independent music and fan music overlap and are easily confused, fan music is a fan activity and is not for the purpose of making profits or making a commercial debut. The acquisition of works and the way to communicate with fans are also different from independent music.
