A bit of an odd request, but does anyone have production music that has fallen in the public domain in the USA due to either not being renewed or having a typo on the copyright notice? I have been interested in public domain media for a while now and I'm curious if there has been any tracks/releases from music libraries that have slipped into the public domain over the years. Example: I've heard that some stuff from BG Library (
