On this Who Won the Month episode of the Greatest Pop Stars podcast, host Andrew Unterberger is joined by Billboard staffers Jason Lipshutz and Danielle Pascual to discuss the big pop stars, rising prospects and veteran greats who were heard from loudest in December 2025 — which, was largely defined by Mariah Carey making chart history and Taylor Swift marking the 'End of an Era.' We each choose our top fives for the month that was, then we talk some disappointing recent performances, and look ahead to who we're most anticipating hearing more from in the first months of 2026.
