Massive B Soundsystem is a dancehall radio station in Grand Theft Auto IV, mixed and hosted by Bobby Konders. Based on Konders' statement that the radio station has been "ten years strong", Massive B Soundsystem possibly began broadcasting in 1998.
Massive B Soundsystem serves as a more commercialized counterpart to the more traditional Tuff Gong Radio, which plays purely reggae music, which dancehall music originates from.
The station is distinctive in that Konders radio edits songs played on the station, and will occasionally insert sound effects, echos and even his own voice into certain music tracks. In addition, Konders will occasionally act as a socially conscious voice of Liberty City and an activist, encouraging listeners to be more proactive towards the plight of the city.
As RamJam FM replaces Massive B Soundsystem and Tuff Gong Radio in Episodes from Liberty City, the station is not available in the compilation's version (disc) of The Lost and Damned and The Ballad of Gay Tony.
