Where can I check if a song can be used in a YouTube video?

Question

YouTube

For example, I don't know what license the music is, but I want to embed it in my video. Can I check somehow?

Answer 1

They say there used to be a chip to check, but it was removed.
As an option: start another channel for tests and upload a test video with music in question into it - after uploading, YouTube will check it with its Content Id. If anything, the reputation of the main channel will not suffer.

Answer 2

If you do not have confirmation of permission to use in your hands, then you are already with one foot in the bath. For you will have nothing to answer in the event of a strike.
