The channel focuses mostly on hit-driven R&B, hip-hop, rock, pop, and dance[1] tracks from the 1990s.

Occasionally, lesser-known songs are played, preceded by the "five disc CD changer set on random" tagline.

The channel's logo features a compact disc in place of the zero, representing the popularity of CDs in the 1990s.

In addition, it also replaced the online-only Super Shuffle channel on Sirius, last heard on satellites in mid-2008.

[2][failed verification] As Sirius's first all-1990s channel since I-90 signed off on November 4, 2002, the channel was jockless from February 3, 2014, when both Jo Jo Morales and KT Harris were let go in a cost-cutting move,[3] until May 26, 2015, when former MTV VJ Downtown Julie Brown, who also hosts the weekend's "Back in the Day Replay Countdown", began hosting the channel on a daily basis.
