Earlier this month, we released our Best Songs and Best Albums of 2015 lists, respectively.

As usual, these year-end lists get people charged up. How could we put Rae Sremmurd's Sremmlife at No. 3 on our list?! Do they even write their own rhymes?! Where's the real hip-hop?! So, in light of all the surrounding controversy of the lists we argue over for weeks, we had an idea: ask the artists.

Who is A$AP Ferg checking for these days? And what's Leon Bridges' favorite song of the year? Here's part four (of five installments) of your favorite artists listing their favorite songs of 2015 and why.

Check out part onepart two, and part three now.
