Vh1 Satellite Radio once existed on XM but the channel was discontinued prior to the merger.

Every week, Hits 1 counts down their top 45 songs, usually ranked by airplay.

HitBound is a weekly program airing on Saturday at 9 am and Sunday at noon highlighting new music on SiriusXM Hits 1.

Songs that debut on SiriusXM Hits 1 primarily start airing on HitBound before "graduating" to The Weekend Countdown.

Notable HitBound guest hosts include Timeflies,[3] Jason Derulo[4] and Britney Spears (as a "Weekend Takeover"[5]).
