The original version of this song dropped on February 15th and featured 50, Kendrick Lamar and Kidd Kidd, but after the feedback from the fans, 50 went back and recorded a second verse over Kidd Kidd's efforts. That version of the record plays over the video, as Fif and Kendrick describe their boss lifestyles.
Street King Immortal has been rumored for about a year now. The most solid timetable so far is spring 2013. We'll see. For now, enjoy the visuals.
