I create video content. I also create ads for bloggers. I recently encountered a requirement that ads contain non-copyrighted music.
Many bloggers are now demanding that music be copyright-free. Because YouTube now constantly monitors content and checks music for copyrights. And in case of violation they block the video.
They can simply block the audio track and then the channel can have problems. This has already been proven by many advertisers. That's why it's very important to comply with copyright regulations.
Now YouTube blocks not only the soundtrack but also the video itself, I even had to delete some of the content in the video to be able to download the video. But don't worry, it's not hard to find a site that's full of copyright-free music. Here's a great service where you can find royalty free music https://inaudio.org/ There are hundreds of tracks and Youtube won't block them. If anything, you can provide a document that this track is copyright free.
