Here's a look back at some of the most popular songs that defined the 2010s.

As 2019 comes to a close, and we find ourselves entering a brand-new decade, we're starting to feel a bit nostalgic for the time that has passed. So, we wanted to take a gander at the 10 most popular songs of the 2010s, year by year.

We compiled our list of songs by using the Billboard's Year-End Charts for each year, from 2010 to 2018. However, seeing as we still have a little less than two months left in 2019, we can't yet determine the most popular song. So, we've taken the liberty of listing what we think is the top song of 2019. (Feel free to agree or disagree with us on this one.)
