Since updating my iPad to ios 6 all of my music has disappeared. For the longest time a cloud was in the middle of the screen. After a day blank album icons showed up. If you click on one of them, all the info is missing (titles, time is 0:00' and no music at all). The iTunes Match data just isn't being sent to my ipad. Major issue. Hope they fix it immediately or I'll have to call them for a refund and cancel. It's never worked that great, but this is a joke.
