As the copyright owner of your tracks, you decide whether or not you want video creators on either YouTube or Facebook to use your music.
LANDR will send your release to YouTube's Content ID database & Facebook's Right Manager database if you choose to opt into monetization.
YouTube & Facebook uses this content library to identify the rightful owners of monetized releases. This also means content is delivered to Instagram, which fans can use to include on their Instagram stories.
If YouTube or Facebook finds a match, LANDR will be able to collect the earnings owed on your behalf.
