Seems like something's wrong with the @GooglePlayMusic app. All new episodes of all podcasts say they're 0.00 minutes long, and when you play them, they'll start playing but everything locks up. It's been like this since sometime yesterday.

Sorry to hear you're having trouble – try refreshing the app by going to Menu > Settings > Refresh. If the issue persists, you can reach out to the Google Play Music Podcast Portal support team for further help: http://yt.be/help/CKt1 . Hope this gets resolved.
