I have about 40,000 tracks in my iTunes library.
As I understand it, in order to add Apple Music tracks to custom playlists, I have to enable the iCloud Music Library, which I can't do with more than 25,000 tracks in my library.
I know that I can work around the problem by splitting my library up into two. But I wonder if there's a simpler solution?
I don't listen to audiobooks very often, and so I'm not using the "Audiobooks" media type in iTunes. If I relabel a music file as an audiobook in iTunes, it no longer shows up in the Music track count, but I can play it just like normal from iTunes on my desktop.
Before I go culling my whole library for tracks to label as books, though, I wondered if anyone had already tried this, and whether it works? It seems a lot easier than breaking everything into two separate libraries, but I haven't seen it suggested in any of the many threads on this issue.
