How do I find my Geometry Dash song files on PC through Steam file browsing?

I can’t find the song file location. I tried looking through Steam>GeometryDash>Propreties>Browselocalfiles. I want to replace my Songs with non-Newgrounds songs, but I can’t find the song locations! I’ve tried %appdata%, but Geometry Dash doesn’t show up in there because of steam file browsing. Where can I find them?
