It plays soul, R&B and funk, and is one of the most chronologically diverse radio stations in GTA IV (and indeed the whole GTA series) as its playlist contains songs from the 1970s to the late 2000s. The station does not appear in Episodes from Liberty City and is instead replaced by Vice City FM.
The station is possibly based on Kiss 98.7 FM and Kiss 100 FM, and may also be based on Vibe Virgin Radio (formerly The Vibe 98.5), which is based in Calgary, Canada, and plays R&B music.
This is the favorite radio station of Roman Bellic and Kate McReary, coincidentally the two people that are possibly killed at Roman's Wedding in either the deal or revenge endings. Niko Bellic also appears to like this station, as he says it has "great music" when asking a taxi driver to change to the station.
Dwayne Forge listens to "Footsteps in the Dark" in the cutscene for Undress to Kill. "Footsteps In The Dark" is also famous for being sampled by Ice Cube for his single "It Was A Good Day", which is featured in the San Andreas radio station Radio Los Santos.
