Out with the old, in with the new!

As we gear up to ring in 2016, it's time to reflect on the year that was -- and all our favorite 2015 tunes.

Mark Ronson and Bruno Mars officially ruled the charts this year, with "Uptown Funk" resting comfortably at No. 1 on the Billboard Hot 100 for a whopping 14 weeks between January and April. Wiz Khalifa and Charlie Puth's "See You Again" scored Song of Summer status with 12 weeks atop the chart, and then, moving towards fall, The Weeknd competed with himself as "The Hills" replaced "Can't Feel My Face" at the pinnacle. Closing out the year, Adele's "Hello" reigned supreme throughout November and December.

But there were so many more breakout hits to celebrate this year, from highly anticipated tracks (Justin Bieber and Sia, anyone?), to 2014 offerings that finally hit their stride (Elle King and Walk the Moon), to delightful new surprise drops (welcome back, Missy Elliott!).
