I listen to Spotify almost constantly. I use it on my 45-minute commute to work and also play it pretty much non-stop during the workday as well. I don't even use earbuds, but full-on speakers. My coworkers hate me. Needless to say, I listen to a lot of damn music. Fortunately, Spotify keeps stats that they release at the end of each year, with your most listened too songs. Below is mine.
I wouldn't go as far as saying this list represents the best song of 2016, but it most certainly represents the best songs of all time. And it would serve as one hell of a party playlist.
It's organized from most to fewest listens.
