Meaning

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.

Examples

1. 推しのVtuberがついにオリ曲出すって！楽しみすぎる。 My favorite Vtuber is finally releasing an original song! I'm way too excited.
2. カバーもいいけどオリ曲のほうがその人の個性出るよね。 Covers are great and all, but original songs really show off someone's personality.
3. オリ曲が100万再生超えたの本当にすごいと思う。 The fact that their original song hit over a million views is seriously impressive.
