Welcome to the latest episode of the Billboard.com Pop Shop Podcast, Billboard's weekly half-hour audio breakdown of the charts, hottest music news and year's biggest musical events. Casual pop fans and chart junkies can hear Billboard.com associate editor Jason Lipshutz and Billboard co-director of charts Keith Caulfield every Tuesday on the free Pop Shop Podcast, which can be streamed on Billboard.com or downloaded in iTunes (click here to listen to the previous episode).

Darren Criss drops in on the latest episode of the Pop Shop Podcast, calling in to discuss the upcoming inaugural Elsie Fest on Sept. 27 in New York (it’s a day-long event celebrating showtunes that he’s co-executive-producing and performing at), his Emmy Award nomination for songwriting, and how he’ll appear in the upcoming TV series American Horror Story: Hotel. Before that, Keith and his guest co-host -- Billboard.com senior editor Katie Atkinson (filling in for the vacationing Jason) -- discuss Justin Bieber’s big debut at No. 1 on the Billboard Hot 100 chart with “What Do You Mean?,” The Weeknd’s launch atop the Billboard 200 chart with Beauty Behind the Madness and our newly crowned official song of the summer, OMI’s “Cheerleader.” We also chat about how Sam Smith will be singing the next James Bond film theme -- and we count down our personal top three picks for the best Bond themes ever. Plus! Our chart stat of the week is about the Billboard chart-topping 10-time Grammy Award winner and Rock and Roll Hall of Fame inductee Linda Ronstadt.
