On this week's episode, Jason and Keith welcome three other charts experts -- associate director of charts (radio) Gary Trust, social/streaming charts manager William Gruger and rock charts manager Emily White -- to debate what 2014's song of the summer will be. Is Iggy Azalea's "Fancy" the odds-on favorite, or is Ariana Grande's "Problem" the one to watch? What about Michael Jackson's "Love Never Felt So Good," Ed Sheeran's "Sing" or Calvin Harris' "Summer"? And don't count Nico & Vinz's fast-moving hit "Am I Wrong," or Katy Perry's latest summer bid, "Birthday." The crew also discusses Coldplay scoring the biggest sales week of 2014, Brantley Gilbert's impressive No. 2 bow, Iggy Azalea achieving a chart feat that only the Beatles have scored before, and the just-launched Billboard Twitter Real-Time Charts, and why they're an essential new part of the charts world. Plus: Jason Derulo's big-butt anthem, HAIM, "I Luh Ya Papi," Vic Mensa, Rita Ora and much more.
