Major iTunes 12.2 Bug is Ruining Music Libraries

A day after the launch of Apple Music, users are reporting an iTunes bug that is wrecking music libraries by scrambling artists, albums and tracks.
Apple's tagline, "All your music in one place," implied there was finally a solution to having your music spread out across different services and devices. But one of the key features aimed at making that a reality, iCloud Music Library, may have been the culprit behind the scrambling of iTunes libraries on Macs.
Apple has not yet publicly acknowledged the problem or responded to a request for comment.
