New submitter eeplox writes "I make nature videos for my YouTube channel, generally in remote wilderness away from any possible source of music. And I purposely avoid using a soundtrack in my videos because of all the horror stories I hear about Rumblefish filing claims against public domain music. But when uploading my latest video, YouTube informed me that I was using Rumblefish's copyrighted content, and so ads would be placed on my video, with the proceeds going to said company. This baffled me. I disputed their claim with YouTube's system — and Rumblefish refuted my dispute, and asserted that: 'All content owners have reviewed your video and confirmed their claims to some or all of its content: Entity: rumblefish; Content Type: Musical Composition.' So I asked some questions, and it appears that the birds singing in the background of my video are Rumblefish's exclusive intellectual property."
