This is a great read for anyone who has music that they wrote and performed, (and paid for) a music video, and then posted it on YouTube. I have personally encountered this issue with my song, Psalm on Danny Boy, where some online Distributor has taken all my rights and money for over 300K views! When I contested it with YouTube and sent them a copy of my copyright, they told me that the case was closed. Huh?? Well that's just sick, I wrote it, I sang it, and I paid some guy a bunch of dough to produce it as a work for hire, and now I'm getting zippo. I hope the below info is informative whether you're an artist, musician, or you just care about what's happening in music and to us artists!
Best, DeDe W. :)
