Purchased Apple Music Downloads

I have recently purchased a couple of albums from Apple and now downloaded them onto my computer. I usually transfer these to a NAS drive to play on a different piece of software [Roon], but it seems Apple has broken this as downloads now arrive as HLS files and when synced with my NAS/Roon they are unplayable. This also applies to old purchases, so beware and if you purchase music, you might want to use something else unless you are happy to use Apple music for everything. Which, of course is a nightmare if you have a good hifi.
