Sending a release to YouTube Music will automatically generate an Art-track in YouTube. An Art-track is a song with an image generated automatically by YouTube, composed by the sound recording, the art cover and all the metadata entered in the platform by the end-user, for example, the artist name or the album title.
Art-tracks are catalogued as audio releases for YouTube, that's why the audio is distributed through the platform and they will appear in the YouTube Music app and Youtube Premium, as well as in the channels/playlists that YouTube decides. They are created for their streaming service and their music products. Also, these Art-tracks are included in the YouTube Music app and YouTube Red subscription services.
