DJ Earworm -- like Black Friday sales or the TBS 24-hour marathon of Love Actually -- emerges every December to usher in the closing of another year. You'll try to ignore it, but the epic mashup of the year's greatest hits will, appropriately, earworm its way into your brain until the Spring Equinox.
This year's eighth installment "United States of Pop" mix is called "Do What You Wanna Do," taken from the Maroon 5 song "Animals." The mix, unsurprisingly, features all the singers you're currently "over" but still secretly listening to, including Meghan Trainor ("All About that Bass"), Iggy Azalea ("Fancy"), John Legend ("All Of Me"), Taylor Swift ("Shake It Off"), Ariana Grande ("Problem"), Idina Menzel ("Let It Go") and Sam Smith ("Stay With Me").
You can listen or ignore it -- just do what you wanna do.
