Yes I think is strictly correlated to the fact they TRIED integrating local content, matched content, offline content and streaming content but in a bad way.
The way My Music and playlists work is confusing, and several tracks are stuck...added to My Music but greyed out, and stuck in the middle...they're added but not available and there's no way to come back until Apple hits RESET on their servers maybe 😉
And I'm in UK so is not local...also the same tracks worked first day, and greyed out from second day..now, do you think Apple will ever reply or we'll have another MobileMe/iCloud failure where no one fixes it? Because in those cases as Apple user were kinda forced using those services, in Music case the other streaming services are going to keep most of their users and Apple will loose big...because is clearly way way behind, this is not even beta testing.
I would not like to be the team responsible for Apple Music now....there are so many bugs, and important ones..
