2015 is coming to a close, and Twitter has unveiled the most popular hash-tags that trended this year. Having been divided into distinctive categories of Music, TV, Tech, News, Politics, Sports, Past-times and Stars, the popular hashtags will allow us to reminisce about the year that was in just about five minutes.

Without further adieu, here are some of the most popular hash-tags of 2015:
