I have purchased albums and songs recently by direct downloading to the iPhone. However today when I tried to purchase an album, it accepted my password then a window came up that said, "Your purchase will be delivered to you in the highest possible quality at no extra charge." I pushed the "buy" button on that window but nothing downloads. I checked my purchase history on my computer but it doesn't show up. Tried it a couple more times and same situation. Has this happened to anyone else?
