I have about 130,000 music and audiobook files, mostly ripped, in two iTunes libraries. I've been feeling great uneasiness about how Catalina would reallocate those libraries, created over more than two decades. Now I read on Macintouch that some Catalina users are finding that their ripped music files are simply disappearing, leaving nothing but the music files purchased from the Apple store. So, I'll prevent Catalina from inhabiting the Mac mini I have dedicated solely to all things iTunes. If this is not promptly corrected my 35 year long relationship with Apple will end.
