However, a series of obstacles staggered F.A.B.'s career momentum. KMEL-FM, the Bay's top urban station, imposed an unofficial but crippling blacklist of F.A.B.'s songs and guest appearances, due to petty personal grievances as well as the perceived slight of his successful show on a rival station, thereby significantly undermining his hometown visibility. Later, his breakout single, "Ghost Ride It," was the subject of controversy on two fronts – a national clamor over the hyphy practice of "ghost riding" described in the song (throwing a car in neutral, then jumping out and walking alongside or riding on the roof as it continues to move) and Columbia Pictures' threatened legal action over the use of the Ghostbusters logo in the video (the track samples the movie's theme song). This caused the video to be first heavily censored and then pulled from television altogether.
