We finish our Greatest Pop Stars of 2024 top 10 countdown this episode with a look back at our Nos. 2 and 1 artists, unveiled this Monday on Billboard.com. Host Andrew Unterberger is joined by Billboard's Mike Saponara and Meghan Mahar to talk about the years in Sabrina Carpenter and Kendrick Lamar (26:30).
