OK, re the lateral thinking,
Apple Music is a great idea that was spoiled by Apple's insistence on the end user activating the iCloud music library, in order to be able to download and listen offline to music provided by the service. If like me, you had curated thousands of tracks ripped from CDs over the years, the iCloud music library, which is supposed to allow you to access your music on all your devices, no matter where you are, had a nasty habit of furtling in your library, in true "Apple knows best" fashion and royally fooking it up. The arrogance of it all was staggering. I won't go into the havoc it caused to my own iTunes library as I had my say on that, earlier in the thread.
Now twelve months down the line, Apple claims to have solved these issues, including the reversal of the creepy policy of applying DRM to music you yourself own when it was uploaded to the cloud. For me, I'm afraid, they lost my trust with that debacle. It took me months to put right all the cock-ups and as recently as last week, I was still finding the odd bit of incorrect artwork left over from the disaster, so you can understand my reluctance to try Apple music again.
Over the past few months, with the help of our Ant, Greg and Richard Dunn, I have resurrected my vinyl collection to tremendous effect. I have built a great new set of valve amps, given my digital listening a shot in the arm, via the superb sounding AppleTV version 4 and have also been spending quite a few bob on the iTunes Store, downloading some really great funk and jazz music. Thanks to BBC6 Music, BBC4 and Jools Holland's programmes, I have become active again, discovering new artists rather than listening to the same old same old; in short, I've rediscovered my musical mojo and am enjoying every moment.
Trouble is, as a result of that rekindled enthusiasm for music, there has come a fair bit of expense on the software and life is too short to be buying digital music. I'd rather reserve that kind of expense for the odd, one-off, nice, 180g vinyl release, if you know what I mean

Never thought I'd ever be saying that, but there you go.
So, what to do? For the sake of my wallet, I wanted to join Apple Music (other streaming services are available) again, but I was not prepared to let that damned iCloud thing anywhere near my music collection; once bitten and all that.
The solution seemed obvious once I had thought of it, so I set about doing a copy/paste, to the desktop of my entire iTunes folder. Due to the large size of the library, it took around three hours for the copy process to complete, so I now had two copies of all the music on my Mac-Mini. The library folder copy was renamed and all the extraneous stuff such as the .xml and .itl files were trashed until only the music and artwork folders remained. I then fired up Swinsian; an iTunes alternative, pointed it at the copied and modified music folder and let it do its thing. 5 minutes later Swinsian had imported all the library metadata and was showing an exact clone of my original iTunes library, with artwork and everything else intact.
Turning back to my original library I fired up iTunes and deleted every one of my ripped CDs and Linn Records downloads from the app, until only my 9000-odd iTunes purchases remained. Only when this process was complete, did I actually join Apple Music.
The iCloud music library started up as soon as the subscription activated and began its cursed upload and match process. It stopped after around two minutes, which was encouraging.
Looking at my local library I searched for files modified 10/10/2016 and found nothing had been touched, modified, fooked about with or buggered up. SUCCESS! My original stuff including all my ripped CDs and copies of iTunes purchases, were well and truly walled off from the iCloud marauder and accessible via the Swinsian app, whilst my original iTunes purchases were still within iTunes and available, plus I now had all the great Apple Music facilities, only this time there were no nasty surprises ready to bite me on the arse.
