PopCrush is rounding up the Top 40 Pop Songs for the month of January to let you know what’s hot in the new year! Our list is based off of what we think is going to be taking over the charts in the first month of 2013. We ranked the songs based on what’s trending, reader favorites, and overall listener reception.

This month, there have been some big changes to our Top 40 Pop Songs list, especially in our Top 5. New to our list and in our No. 3 spot is the Lumineers, who has been topping the charts with their single ‘Ho Hey.’ However, they were no match for Bruno Mars, who's single 'Locked Out of Heaven' jumped from No. 4 to No. 1 on our countdown.

Newcomers to our Top 40 Pop Songs list is One Direction's 'Little Things' and Maroon 5's 'Daylight.' Both tracks were just released recently and are already starting to climb the iTunes and Billboards charts. We're expecting these tracks to be huge hits in 2013 and to fall in our Top 10 pretty soon.

Other new additions to our list include T.I.'s 'Ball' featuring Lil Wayne, Wiz Khalifa's 'Remember You' featuring the Weeknd, and Juicy J's 'Bandz a Make Her Dance' featuring Weezy and 2 Chainz. Check out the rest of our Top 40 Pop Songs for January 2013 to see if your favorite song made the cut.
