On "Not Top 40," songwriting veterans Cal Shapiro and Anson Seabra rate, reminisce, and ramble about all things popular music. Combining interactive segments, interviews, and plenty of completely off-topic side conversations, each episode delivers an entertaining and informative discussion on everything from the current state of the Billboard charts to why Cal no longer raps about cloning sheep. This is a podcast for music lovers, stat geeks, or anyone who just wants to hear two friends argue for 45 minutes about whether *NSYNC was better than the Backstreet Boys.
