What is an Art Track?
An Art Track is an automatically generated YouTube version of a sound recording. An Art Track consists of the sound recording, the album art, and metadata about the recording, such as its title and artist name.
The purpose of Art Tracks is to provide a single official, label-sanctioned YouTube version of every sound recording. Currently, official music videos are available for recordings only when a label or artist invests (non-trivial) time and resources into producing one. Art Tracks automate the creation of versions for recordings that don’t have a produced music video.
YouTube creates one Art Track for each sound recording that you upload using the YouTube Music DDEX feed or the "Audio - Art Tracks" bulk upload spreadsheet. It identifies recordings based on their ISRC, release identifier (UPC, EAN, GRid), and label. YouTube will create Art Tracks for each unique combination of these fields.
Art Tracks fill in the gaps to ensure that YouTube has a complete music catalog. They appear in the same places as produced music videos, such as on the YouTube topic channel for the main artist, in album playlists, and in search results, including watch cards for the artist. YouTube prefers the produced music video for recordings that have one.
