YouTube Music
When you distribute your music to YouTube Music, YouTube will automatically create an Art Track. An Art Track is an automatically generated YouTube version of a track on a music album, and consists of the sound recording and the album art.
You keep 80% of the revenue earned through YouTube Music.
YouTube Sound Recording Revenue Collection Service
TuneCore offers a separate service that allows you to generate additional revenue via YouTube Content ID. This service uses YouTube's Content ID tracking system to identify when other YouTube videos are using your music (even if it's just a clip), and places ads on those videos so that you can make money when they're viewed.
You keep 80% of the revenue collected through this service, and it can be utilized in addition to YouTube Music.
