Where to find music without copyright

I want to build an youtube music channel but i don't know where can I find music without copyright? Also, I don't want to put a link to another youtube music channel. Yes, I agree to put link to creator social media's profiles, but not to another music channel.

I can put the link to soundcloud.com but i said that i do not want to put to other youtube music channel that will be my competitions. And in all description from Audio Library they say that they also want a link to their channel. Same with channel like NCS.
I don't want this type of chanels from where I can get my music.

Same with the site that you put here:
"If you use Free Background Music you MUST put in the description of your
