Now That's What I Call Music! 56

The 56th edition of the popular series serves as a snapshot of the summer of 2015 in mainstream popular music, including huge hits from pop titans Taylor Swift, Selena Gomez, and Demi Lovato; fan favorites the Weeknd, Fall Out Boy, and Ed Sheeran; and up-and-comers Charlie Puth, Rachel Platten, Shawn Mendes, Skylar Stecker, and Elle King. Even Silentó's popular dance craze/meme "Watch Me (Whip/Nae Nae)" makes an appearance. The "featuring" roster alone (Adam Levine, Kendrick Lamar, A$AP Rocky, Meghan Trainor, and John Legend) could warrant its own volume. ~ Neil Z. Yeung
