@GhostOnTheHalfShell @krusynth I still have an iTunes Match subscription. Never let it lapse, and it's still happily matching tracks and off-site storing a good majority of my library, providing good quality AAC-256 DRM-free replacements for some of my lower-quality older MP3s.

27,423 tracks.
No duplicates.
(Mixes yes, straight dupes no.)
77 days playing 24/7.
I am my own radio station.

There's been some weirdness re: a few artist back-catalogs, but I still have the record of them in my lib.
