Anecdotally, I've had no issues with iTunes 12.2.*
Granted, my usage isn't everyone else's but I have to wonder if this issue has something to do with the format (i.e. MP3, WAV, Lossless, etc.) of music in the library, and/or the quantity of music (>5k songs).
I installed OS X 10.10.4 and iTunes 12.2 on the same-day it was launched; backed-up my computer, clicked "Update All," and left it to finish updating. I installed I'm an iTunes Match (iTM) and [now] a Apple Music (AM) subscriber. My complete music library is just over 4k songs; approximately 1/3rd of which being iTunes-purchased, the rest being CD rips or Amazon MP3s.
Post-update, iTunes launched, asked me if I want to subscribe to AM, and refreshed all of my music album art--all of it appears (knock on wood) legit. --This was with a local copy of the music.**
When I updated on my 2nd Mac, I had no local copy of the music--all was in iTM. The update went fine. To test, I downloaded a local copy of all the music from iTM, and no problem(s). --This was with no local copy of the music (all streaming).***
Lastly, I updated my wife's 15" MBP,**** and her music (knock on wood) hasn't gone anywhere.
The only issue(s) I've had with with AM thus far remain with my iOS devices: The only one I'm able to demonstrate reliably is [All] music not showing when selecting an Artist. You have to go back to the Artist list, then go back into the artist for the [All] menu to show.
I'd be very curious if those affected have a similarity in their respective libraries, perhaps demonstrating either a causality and/or correlation between those who experience this issue vs. those who don't.
* The sole exception being iTunes no longer automatically launches when I connect my phone or iPad to the Mac.
