You are absolutely right. I found many Projects and YouTube Channels in the past which were claiming "no copyright" music but have either many different crediting rules in small print or have claimed ownership via YouTube or Soundcloud. As a Music Artist I found out early, that Music-Copyright is not trivial - just because someone says a song is copyright-free and submit it, it really is - still someone else can claim ownership rights on parts of the song etc. I realized that I can't easily get some songs from the internet and put them online. I decided to give my own music away for free as I can assure the rights and I only used license free material in the music. In the hope others will follow. To answer your question: All submitted songs to wowa.me will be checked and reviewed one at a time on quality and ownership. I use tools to ensure this song is not already registered etc. Furthermore every submitter has to accept terms of submission. But you got me on two important things: 1. Submitting System needs to validate email-realness via double-opt-in or so. 2. How multiple commercial usage can work? Example: artist uses the free beat/soundtrack and publish this new song (with vocals) to all platforms (spotify, itunes and youtube network) Question: Will YouTube copyright mechanism take effect if another artist uses same free beat with other vocals? thanks
