Your release may not be available on Deezer due to their transition into an editorial platform. Deezer reserves the right to remove music that doesn't meet their quality standards or align with their mission to make it easier for music artists to be heard.
Deezer aims to maintain a platform free from noise and clutter. They have removed tracks they consider to be noise, albums comprised of copies of a single track, tracks that haven't been favorited, and tracks that haven't been listened to in the past year.
