When the battle song begins, the battle song is the bloody and burning BGM music and songs. In the works with the theme of blood, the fighting music is mostly the burning system, so it is called the battle song, but the battle song mentioned from the battle song is not limited to the fighting theme, as long as it is the burning system BGM. Warfare songs are often sounded before the battle is about to start (or the plot is about to enter a climax), and the atmosphere will soon become boiling with blood, which can also mobilize the emotions of the audience. Whenever BGM rings, the audience who watch the dead houses on the barrage video website will brush up the barrage battle song or take away from Gogo. There are also funny barrage such as hearing this song, I want to ride my dog to the battlefield or hearing this song, and I can see from my dog's eyes that it wants to ride me to the battlefield.

Warsongs usually appear when a BGM with special significance rings. For example, in the Japanese drama Lonely Gourmet, every time the protagonist eats at full throttle, a specific piece of music will ring, and the barrage will be covered with neat warsongs.
