6. Mark Ronson featuring Bruno Mars, "Uptown Funk" "Uptown Funk" will be played at every wedding reception you attend for the rest of your life, and its opening notes will fill you with neither embarrassment nor dread. By the most reliable rubric, then, "Uptown Funk" is a great pop song.
8. The Weeknd, "Can't Feel My Face" An infectious bassline that trembles like a rubber pencil propels an ex-underground R&B lothario's triumphant transformation from neo-Prince to neo-MJ.
9. Adele, "When We Were Young" Pop's old soul goes full Bette Midler, with a welcome dash of "Piano Man's" dive-bar pathos thrown in for good measure. Suffice to say, the next round's on her.
10. Erykah Badu, "Cel U Lar Device" Leave it to Miss Badu to flip the script on the year's most familiar pop curio and make it sound like a transmission from another, much more chill galaxy, where the cell phone reception is blessedly shoddy.
