Hi - I just got a new iMac and I'm going to set up my iTunes library again (my old one is 10 years old and got screwed up with Apple Music). I have 3 sources I want to pull from for my music - 1) CD's I've purchased 2) Music I've purchased via iTunes 3) Apple Music I plan on ripping all my CD's into iTunes (Lossless quality) and want those files to stay there. I also am going to re-download my iTunes purchases. Lastly, I plan on downloading albums via Apple Music. How do I make sure that the music I'm adding via CD and iTunes doesn't get deleted with this Apple Music/iTunes bug?
