When I upload and I have background music, I keep getting copywrite claims, I clearly credited the music in the video, but the description keeps clearing out during the upload 
Your best resource will be the Copyright section of our Help Center, start with these top FAQs: https://goo.gl/FzBC2x . You can also review info on fair use, creative commons, and our troubleshooter linked from there. Also, for the description does this happen across device?
