The Greatest Pop Stars of the 21st Century

This week, we've got two artists who go back even further than the beginning of the 21st century: Shakira & Jay-Z. Host Andrew Unterberger is joined by Isabela Raygoza and Sigal Ratner-Arias of Billboard Español to talk about Shak's emergence as a global superstar and how she's maintained that status for 20-plus years, and then (38:38) Billboard Hip-Hop's Angel Diaz and Michael Saponara tap in to discuss Hov's reign as the closest thing to a consensus greatest rapper of all time, and how he also intersected and helped shape the pop world at his peak.
