I have a ~32GB music library. It is comprised of about 70% songs I ripped from CD's I own, 15% iTunes music purchases, and 15% mp3's I have created myself from various hobby bands. All of this is currently managed by iTunes on my iMac, and is one of the last remaining anchors keeping me from moving completely to my iPad Pro. I do not want to subscribe to Apple Music for $10/month. Is there any other way to manage my music archive without involving iTunes? I am particularly concerned with a future time when I upgrade to a new iPad and cannot move my music library to it without iTunes. Any help appreciated.
