Anyone else seeing this? I've been casting Google Play Music from my Chromebook to my entertainment system using my 1st gen Chromecast today, and noticed that when playing my Thumbs Up playlist on shuffle, it seems to freeze after anywhere from 5 to 10 songs. I see the loading rotating circle icon next to the track that wants to play, but it just never loads. The Play button at the bottom is greyed out, although I can click the Skip button--but the next track still has the loading circle and never plays. I have to stop casting first, then skip to another track, after which it starts playing again.
