I'm with you, there was no warning that this was going to happen with the update. Frustrated that I can't get my songs originally uploaded from CD, only content downloaded directly from Apple... Further, not all of the songs I've downloaded are even there. Content must still be there based on available space; Apple care not providing any assistance or suggestions either and I didn't sync with computer prior to update. If I sync now, will it all come back and how much of my non-cloud content will be lost in the process???
As a share holder and typical lover of all things Apple, I have to say, sorely disappointed in this product, process and customer service. (Rather Microsoft-y of them... Hope this is not a snapshot of the future.)
