Listen to the latest episode of Billboard.com's weekly charts 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 the previous episode).

Jason and Keith break down the fascinating Twitter "feud" between Britney Spears and Iggy Azalea: was it all just a misunderstanding, or were shots actually fired? Later, the guys take on Demi Lovato's new single "Cool For The Summer," Selena Gomez's Top 10 debut with "Good For You" and (sort of) debate which song will end up the bigger hit; "See You Again" is still on top, but OMI's "Cheerleader" could be coming for that No. 1 spot as early as next week; new Hot 100 hits from Janet Jackson and Nicki Minaj; and the unlikely triumph of Breaking Benjamin on the Billboard 200 albums chart. All that, plus Miguel vs. Sara Bareilles, an MJ chart stat of the week, Jason singing some of "A Whole New World" and much more.
