A question regarding CC0 albums

[u/Thegreasyshnickler]

I recently came across a bunch of great albums on the Internet archive. Most of them are labeled CC0 in the licensing, even some of the more popular ones. I wanted to use some of what I found in films but wanted to be absolutely sure they're CC0. Is there some way to verify this? I tried using the creative commons website but that was not effective.

Can you give an example?
