I noticed that no matter how I synchronized my phone, the music would be organized properly, but within the hour all of the music data was wrong. I have never had a device that actually changed the music files. I find this absurd and presumptuous for a device to force unapproved, permanent information on your media.
I finally found a setting under System Settings \ Applications \ Music + Video. Turn “Connect with Xbox Music” OFF.
You will lose a few minor features, but your music will be safe.
