It would be nice to see a thorough
compare/contrast/conflict analysis of Home Sharing vs. Family Sharing. I'd do it myself if I wasn't worried about inadvertently locking out an iPhone or iPad for an account for 90 or 365 days.
Article says "Non-shareable content includes songs added to iTunes Match from outside of the iTunes Store,"
If iTunes match successfully matched a CD, your family will have access to this CD. However, it seems that if the CD was not matched, and was instead manually uploaded from your comp to Match for your account, they can't access it.
I must've tried to match one particular CD four or five times, ripping to both AAC and MP3 at various bit rates before I found one that would match every song. Weird behaviors, too, where one song wouldn't match at 256 kbps MP3 and four
other songs that wouldn't match at 320 kbps AAC. Re-ripping AAC at the iTunes defaults seems to have the best luck with the CDs that I've matched so far but, man, what a PITA. More stubbornness on my part than anything really useful except, as you say, if you can't share uploaded songs with your family's iDevices.
For having been released three years ago, iTunes Match really feels like an abandoned beta. I
get that they don't want people to be able to just rename any old MP3 to "match" songs they may actually not own, but IMO the current match algorithm errs far too much on the side of cautiousness.
At some point, I guess you give up and go back to separate iTunes libraries and copy MP3s back and forth?
That's too bad, and I don't even remember how to check what was matched successfully or not. This is part of what is just supposed to work. I know I have at least a couple CD's that are in the iTunes store available for purchase, but still didn't get matched correctly, so it uploaded it. Because of this, my family can't listen to it? Smh.
One of the columns you can add from the Playlist view in iTunes is iCloud Status, with various statuses like Matched, Uploaded, Purchased, Not Eligible, etc. that you can sort or filter on. But, you're right, it shouldn't be that hard.
