Now That's What I Call Music! 52

When the 52nd volume of the Now series was released in November 2014, it featured only one song -- Meghan Trainor's throwback pop "All About That Bass" -- that had reached the top of Billboard's Hot 100. Six selections, however, had already peaked within the Top Ten, including Jessie J, Ariana Grande, and Nicki Minaj's "Bang Bang," Minaj's "Anaconda," Grande and Zedd's "Break Free," and Nico & Vinz's "Am I Wrong." As usual, the series attempts to provide a boost to some developing artists and under-performing singles, such as Alex & Sierra's "Scarecrow" and Eden XO's "Too Cool to Dance." ~ Andy Kellman
