Pop Shop Podcast: Ask The Pop Shop, Carrie Underwood, Lorde, Adele

Listen to the latest episode of Billboard.com's weekly audio breakdown.

Welcome to the latest episode of the Billboard.com Pop Shop Podcast, Billboard's weekly half-hour audio breakdown of the Billboard 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 associate director of charts Keith Caulfield every Thursday on the free Pop Shop Podcast, which can be streamed on Billboard.com or downloaded in iTunes (click here to listen to last week's episode).

Jason is on vacation this week, so Keith is joined by special guest Gary Trust (Billboard's associate director of charts/airplay) for a charts-filled Pop Shop Podcast. Keith and Gary break down Blake Shelton's second No. 1 album, Bringing Back The Sunshine, how Adele's 21 album has reached a new major sales milestone and what albums are on the horizon that might be blockbuster sellers.

They also discuss how women dominate the top five of the Billboard Hot 100 for a record fifth straight week, and why women are doing so well at top 40 radio; how Carrie Underwood blasts onto the Hot 100 with her new single, "Something In the Water," and Lorde also arrives with her latest, "Yellow Flicker Beat." Also in the mix: Aretha Franklin achieves her incredible 100th chart hit on the Hot R&B/Hip-Hop Songs chart with her cover of Adele's "Rolling In the Deep," while the guys take questions from Twitter about Demi Lovato, the Jonas Brothers and more.
