It's hard to believe that it's been a year since Google's streaming dongle arrived on the backs of TVs, bringing easy streaming chops to the masses. As a proper celebration, the folks in Mountain View are thanking both current and new Chromecasters with three free months of Google Play Music All Access -- starting today through September 30th. The company has been keen on adding new features to the accessory regularly, and in the festive announcement teased the ability to beam content while away from your WiFi and customizable homescreens as upcoming additions. Heck, with that bit of subscription savings, you'll almost have enough for a second unit.
