"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.
"I Want You" is included on the GTA IV soundtrack available on iTunes.
The Vibe so far is the only R&B station with the most diverse playlist as it contains songs from every decade from the 1970's-2000's. Other R&B stations before would contain songs for a set time period (i.e.CSR 103.9).
There is a radio station in Calgary, Alberta called Vibe Virgin Radio. The former name of Vibe Virgin Radio is The Vibe 98.5. Similarily, The Vibe 98.5 plays R&B music. Rockstar may have based The Vibe 98.8 off of Vibe Virgin Radio or it may be just a coincidence.
The Vibe Plays in the Triangle Club and in the Honkers Club. But in the Episodes from Liberty City, the Music is Changed to Electro-Choc, while in the secret VIP room, the radio station is changed to Vice City FM, which is normal since The Vibe is replaced by Vice City FM in the EFLC Version.
It is possible that "Me & U" by Cassie was removed from the final game because it was also used in Saint's Row 2
