I had a video on YouTube for 3 years with no issues.
Suddenly I get a "copyright infringement notice".
I checked out the video. It was me talking to the camera......but.....in the background you can very faintly hear a radio one of the builders had on and it's playing a song very quietly and I can't even make it out. I played it several times and I couldn't hear it clearly - and definitely not over my own voice.
Apparently, YouTube think it was a song by The Eagles. I guess I have to take their word for it.
They have a "remove the song" option.....which actually wipes the entire sound track - including my narrative - and gives me a chance to replace it with music....only.
I've been getting this stuff increasingly over time - including songs from freemusicarchive.org that were explicitly Creative Commons / Attribution Only - then later the author uploads the same song to some other site and doesn't read the fine print (giving them rights)...and I get hit with a copyright notice despite complying completely with the CC requirements in force at the time I made the video.
Copyright is a scam. I now have less respect than ever for it....and I never had much.
YouTube never respond to the disputes....I learned that years ago.
Now I just delete the videos. The imaginary rights holders can go jump....or whatever.
