The end of the year is a time to reflect on months past, ready for the months ahead, and turn up the volume in between. As the clock runs out on 2013, we can't help but reminisce on the times we've had—especially those set to the biggest songs of the year. From summer anthems that “Blurred Lines,” to surprise bangers that had us Bing-ing “surfboard,” (oh, Beyoncé, behave!), this playlist captures it all. It's a little bit country, it's a little bit rock ‘n’ roll, and a whole lot of chart-topping, too. With Lorde, Haim, Johnnyswim, and Kanye West setting the tone, relive 2013 with 50 of the year's top tunes.
