I also think it's a POS. Apple have not addressed the frustrations of users who ave large libraries of classical music.
Somebody else has a classical library?!?! Yay, I'm not alone!
Okay, speaking as someone with 3964 "songs" (some "songs" for you non-classical people can run 10, 15, or more minutes!) taking 41.62 gb of space with a total runtime of 15.2 days, what do you find wrong with iTunes? I'm not criticizing, I just want to know.
For me last year, iTunes Match wasn't up to the task, even though I was able to upgrade a whole lot of my ripped cd's to 256bit aac. But it screwed with my album covers a lot and even when I reset my own album art to what I wanted, iTunes match would put it back again. And some albums would "match" everything except 1 song. (Not just classical, either: Billy Joel's Greatest Hits Vols 1 & 2 matched 24 out of 25 songs, but of course you could BUY the 25th song if you wanted!) So I finally turned it off and emptied out my icloud library entirely. I let the subscription expire a few weeks back.
Again my biggest complaint is the tiny displayed size of the album art. Must REALLY be small on a 15" rMBP!
