I didn't think I'd recommend that users not upgrade to a new version of iTunes, but this time I will. If you have a carefully curated music library, manually tagged, with painstakingly chosen or scanned album artwork, stay away from iTunes 12.2. Especially if you plan to use iTunes Match, Apple Music, or iCloud Music Library.
If, however, you don't have much music, it probably won't affect you. You might find that iTunes 12.2, with Apple Music, is just fine. It's probably fine for a lot of people, but it's toxic for music libraries that have been maintained with care.
Apple, you've let me down.
