iTunes radio - trouble buffering/playing
iTunes radio on Mid-2012 13:" Macbook Air (10.8.5; iTunes 11.1) is frequently not beginning playback of a new song; instead I just get diagonal stripes in the time/buffer bar, and it will stay in this state indefinately. If I skip to the next track, it generally bufferers/plays...but a song or two later I get the same hangup.
The Internet connection should not be an issue (I just tested it at 14Mpbs down / 12Mpbs up / 12ms ping).
Is anybody else seeing this? My first thought was that it was just that Apple's servers are overloaded with the recent releases...but my iPhone doesn't run into this issue.
