When exclusive copyrights are held to the sound recordings you deliver, the assets can be claimed through Content ID (‘asset rights claim’ in Fuga Next). Revenue will be earned when those assets appear in user generated content on Youtube.
Not all content is appropriate for claiming through Content ID. You should not claim content for which you don't have sufficient rights. You are responsible for avoiding claims that result from misidentified content or claims that interfere with authorised uses of content.
The following rules apply in deciding that content is ineligible for claiming through Content ID.
Exclusive rights
Any type of sound recordings for which exclusive copyrights are not held. This involves covers, unofficial remixes, karaoke or sound-alikes. Compilations, live recordings and various artist ‘best of’ releases are generally ineligible, as copyrights to all sound recordings are likely not held.
Public domain content
Sound recordings or video footage of compositions in the public domain. Copyrights on the compositions have expired, making the content ineligible for monetisation.
Generic content
Insufficiently distinct content, also called ‘generic content’, involves nature sounds, ambient sounds, ASMR, white noise, binaural audio, sound effects, loops, soundbeds, demos and meditative content (fe. music for sleeping, etc).
Royalty free content
Royalty free production music libraries typically licensed for use in game, film, TV or other soundtracks.
Recording of a non-musical work
Audiobooks, podcasts, speeches, comedy recordings, film recordings, prayers, video gameplay footage.
One song in one asset
Assets must contain one piece of intellectual property (ie. a song). A continuous mix, DJ mix, mashups, countdown lists, or compilation of tracks within one asset is ineligible.
Video game soundtracks
Sound recordings created primarily for use in a video game, such as the original score or background music accompanying a video game, which are owned by the video game’s publisher. This policy does not apply to licensed popular music, not originally created for the game.
