Itunes on new OS
I have a rather large Itunes library, which I am still running on Mojave 10.14.6. I've been reluctant to upgrade my OS for fear of how this might affect my library. Fox example, will I still be able to add to the library from all sources including uploading from cd's and from Youtube-video-to-MP3 conversions? I would like to upgrade my OS but don't want to lose thousands of tracks.
Any advice? thanks in advance
