A year ago this week, the Android Market sloughed its cocoon, emerging triumphant and sassy as a Google Play butterfly. To celebrate the metamorphosis, Google's giving stuff away, for free, all week.

Today's promotions include free songs, free apps, free books, a free Breaking Bad episode, and—if you're sitting down, are you sitting down, please sit down—in-app purchase credits. Go! Enjoy! And no one tell Google that your birthday is when you're supposed to get presents, not give them away. [Google Play]
