I need copyright-free music for advertising.

Yes, we were given content requirements. We practically complied with all the requirements, but the copyright for the music didn't work out a bit. As a result, we needed music without copyright and with documented proof.

Such problems often arise, many who shoot content for YouTube, with such problems encountered. Use the service with no copyright music. There is a huge amount of different music for different categories. It does not take much time to find what you need. The cost of subscribing to such services is not very high. I have tried so many different services, but I can't find such a big selection of music anywhere.

I agree with you wholeheartedly, and even when they increase the security of a front door, fence, or other barriers, I continue to use the house intercom system*to play music, which can be connected to your door locks so that visitors can open doors remotely.
