Quintin Barry's Top 20 Countdown

Quintin Barry's Top 20 Countdown (commonly abbreviated to QB20) is an internationally syndicated, independent radio program created by Quintin Barry and is distributed worldwide by QB Productions.

As its title implies, QB20 counts down the twenty most popular songs in the United States of America, from #20 to #1. The charts currently are based on data from Mediabase, and published in the Tuesday Edition of USA Today.
