意味

Original song; a song that is not a cover but composed by or for the artist.

オリ曲 is short for オリジナル曲 (original song). In contexts where covers are common — like Vtuber streams, Nico Nico Douga, or indie music scenes — distinguishing original songs from covers is important. Having an オリ曲 is a milestone for creators, signaling they've moved beyond covers to producing their own music. For Vtubers especially, releasing an オリ曲 is a major event.
