Podcasts come to Google Play Music at last today, but unfortunately, the service is only for US and Canada residents. One of the beautiful things about podcasting is anyone in the world can hear it (in theory, anyway), so this is quite the detriment for many would-be users. We've contacted Google for comment and will update this story should we hear back.
Included features: podcast suggestions, subscriptions, notifications; missing features comprise mark as read, playback speed, and RSS, among others. In other words, this is a pretty bare bones service. On the plus side, the design appears great.
To try out Google Play Music podcasts for yourself, update the app through the Play Store now.
