David Sparks on Apple Music and iTunes Match:
> The problem arises when you first set up iCloud Music Library and it overlaps with your prior iTunes Match tracks (that you presumably purchased and should be DRM free). Early tests, including this one from Kirk McElhearn, are indicating some of your iTunes Match tracks are getting DRM applied to them when they shouldn’t.
This whole interaction really scares me. It is why I probably won’t even give Apple Music a try for a couple of months.
