2015 came to a close faster than the time it takes to say "Auld Lang Syne," which means there is no time left to look back at all that happened.

Vox has boiled down the last 12 months to four minutes in this action-packed video where we look back at some stories that captured our attention, our imagination and our hearts.

From Freddie Gray and the legality of same-sex marriage to Donald Trump's presidential run and more mass shootings, this clip brings it all back and shows the wide array of subjects that made headlines and had us talking. And those are only a few of the stories that were on the nation's mind this year.

So, take a look and remind yourself of what was relevant and important in 2015. And good luck trying to determine the biggest story of the year -- there may be just too many to choose from to make the right decision.
