What about fanmade videos, like original animations or the more common AMVs (aka MAD)? There is also 3D stuff like the popular MMD
AMVs can also be edited by several people which are then called MEP and original animations ones MAP
- List of AMV & Site Resources - AnimeMusicVideos.org
- Tag “multi-editor project” - MusicBrainz (edit: was “mep”)
In the case of world.execute(me); I’ve used the music video relationship to link the fan videos. If this is not correct the documentation needs to be clearer. Right now it doesn’t say it has to be an official music video.
