iCloud Music Library bug is raining on Apple Music’s parade

The launch of Apple Music and Beats 1 went as well as could have been expected on Tuesday, but an iCloud bug widely reported on Wednesday is spoiling the party for some.
The problem relates to a new feature called iCloud Music Library, which is a rebranded version of ithe library-liberating Tunes Match feature that is now bundled in with Apple Music subscriptions.
According to multiple reports, many users who’re switching on iCloud Music Library in iOS 8.4 and iTunes 12.2 are none-too-pleased by the results
So, to sum up, it’s wreaking absolute havoc on carefully curated iTunes libraries.
Conversely it also seems to be restoring content users have previously deleted from iTunes Match.

In a lengthy thread on the Apple Support forums, a poster identified by his username as Scott B Silverman explained: “I’m having the same issue and am incredibly frustrated. Literally years worth of work – collecting music, creating playlists, tweaking metadata, downloading album art and more.
“After “upgrading” to iTunes 12.2 my library is now showing 2 or 3 copies of some songs/albums, my playlists have been gutted, some track metadata has been changed to be incorrect, and old albums that I deleted from iTunes Match have suddenly reappeared in my library as “in the Cloud.” What a disaster.”
No word yet on whether Apple is working on a solution, but there are some workarounds currently floating around on the support forums.
One method in particular advises users to retrieve an old iTunes library from a backup, while another less attractive option involves ditching the iTunes Library completely and just re-adding everything (that’s available) via Apple Music.
