Okay seeing how I got no insights on this, I was able to fix it so I figure I'd help out with this.
I uploaded my video and one of the songs got flagged and was labeled as a song that was immediately to be muted or changed because of copyrights. I immediately tried contacting WMG to try and get a youtube license of some sort and was even down to pay some money since I worked really hard on the video and changing the song was not negociable for me. I eventually ended up uploading it to Vimeo while I got an answer from them.
3 weeks I didn't get any type of response at all from WMG so I said fuck it uploaded it to youtube and disputed the copyright claim. I just wrote the following disclaimer on the dispute form and on the video description. While also stating on the form that this was just a video of me and my friends and that I was not making money of it, nor was I going to monetize it.
"Copyright Disclaimer: Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use."
2 days later the video was up and running.
Hope this can help some of you!
