It's hit and miss, depending on the platform. Youtube, Insta and Facebook have become the worst. Vimeo is somewhat better.
Off topic, here is how the music business works. A song is recorded and published. Unless something special is negotiated, the writer owns 100% of the writer's royalties and the publisher owns 100% of the publishing royalties. It's confusing because that's 200%. But writing royalties and publishing royalties are completely different. The writer earns money when the song is played or used (on the radio, in a movie, etc.) The publisher makes money AND MORE IMPORTANTLY - controls where the song is used.
The publisher is the watchdog for copyright infringement on social media.
For instance - Syn has sent me links to A7X stuff being used on Youtube, (kids reacting to their songs, etc.). He loves it and thinks it's hilarious. Then the publisher yanks it down almost immediately. Publishers are only interested in making money off of the songs. No matter how harmless, if the songs are used without permission, there is no money.
Publishers now have programs (similar to Shazam) that scan social media and identify copyrighted material so it can be removed.
As far as artists go - unless their music is being used in a derogatory way, (like promoting a political candidate they don't agree with), they couldn't care less. And even if they did care, there is nothing they can do. The publisher controls the song.
Welcome to the music biz.
