@jpgoldberg @sillygwailo I’ve been using that since it came out and love it, but I’d swear I’ve lost some tracks too. Not enough that I can be certain. It’s one reason why I still keep a big folder on a local Plex drive.
It also does NOT appear to be shared through family sharing — you need to be logged “into iTunes” using the same account that pays for Match. I’d been hoping I could move the family to using their own AppleIDs with Apple One (or whatever it’s called) for individualized playlists, but then they lost all our ripped CDs, so that’s a non-starter. (OTOH it’s mostly Floyd bootlegs they’d lose so probably nobody cares but me…)
