Retaining music after decommissioning device
A while ago, my music was on an NAS attached to a Windows machine. My rMBP fed off the same files via my wifi network (not Apple's Home setup). With that configuration, I subscribed to Apple Music so I could have my music available on all devices. At some point, I decommissioned that Windows computer. The NAS still exists, but is detached. My existing devices shows my music library as in the cloud. I would like now to cancel Apple Music. I'm concerned that, once that happens, there will be no further downloads possible of my music. There does not appear to be any way to bulk download the library. There are thousands of tracks. What can I do to export or otherwise retain my music library after canceling Apple Music?
