The year is about to end, and as is the tradition almost every where, it's a time for reminiscing and retrospectives. That's true back in the analog days and still true even in today's digital age. Being one of the biggest sources of digital content, Google Play has some insight into the hottest trends of the year. So naturally, Google is in the position to reveal what's hot and what's not as far as apps, music, and movies go.
