You can glance over almost any music magazine or publication this time of year and find endless “Best Of” suggestions: “The 50 Best Songs of 2015,” “The Best Albums of 2015,” “All of My Favorite Songs and a Few That I Think You Should Hear Simply Out of Moral Obligation,” etc. When I set out to create a New Year’s Eve playlist, I also thought back to all of the stellar music that has made 2015 so memorable. Still, I wanted to hear what’s next.
