Top 20 on 20 (or just 20 on 20) was a commercial-free, interactive hit music satellite radio station.

[1] The channel played everything new from rock to rap, with the songs chosen by online votes to the XM website.

[2] Among the changes included a cut in the countdowns by 50 percent, adding live DJ's throughout the day including the return of Priestly and Michelle, and having celebrity countdowns on Fridays at 9 pm Eastern.

By September 2009, the channel was removed from Mediabase's reporting panel, and aired music mostly sourced from Sirius XM Hits 1; however, the channel's programming was still different from Sirius XM Hits 1.

Until February 9, 2010, Sirius XM Hits 1 and Top 20 on 20 was heard on DirecTV channel 816 until DirecTV has stopped carrying Sirius XM programming and replaced it with another music service called Sonic Tap by DMX.

The new station will focus on Rhythmic pop hits from the 21st Century with core artists including Beyonce, Britney Spears, Christina Aguilera and Black Eyed Peas.
