iTunes 12.2 & Apple Music subscription made almost all tags corrupt
Just updated to iTunes 12.2, subscribed to Apple Music and after syncing my library with iCloud it broke almost all my tags in library. Now my list of artists has a lot of duplicates, but in fact these are different artists, just somehow they were renamed. Same goes for songs, they have incorrect titles taken from other songs, etc, etc, etc. So, how do I revert this back to normal state?
That's how it looks like:
