I didn't know this iCloud Music Library thing was automatically turned on in iTunes on my iMac. I do like this feature but I only want to have it turned on with my Macbook and iPhone. Now I have a lot of tracks from my iMac mostly recording or audiobooks that cluster up my iCloud Music Library. I don't see an option to clear the iCloud Music Library, and manually deleting 1,201 tracks would take me two and half hours. Is there a way to remove all tracks from iCloud Music Library?
