 " Bop Gun " was the first episode to feature Chris Tergesen as music coordinator , and thus more music is featured in it than any previous episodes . During the opening scene , the song " Killer " by Seal and Adamski plays over a brief montage of images of Vaughn Perkins , just as Tweety and Marvin preparing to rob the Ellison family . When he is arrested , Marvin is wearing headphones , listening to the Public Enemy song " <unk> off My Back " . The Eric B. & Rakim song " Chinese Arithmetic " plays during the scene in which police simultaneously interview Tweety and Marvin . " Feels Like Rain " , by the blues guitarist and singer Buddy Guy , plays as Howard arrives to talk to Vaughn , and when she leaves after talking to him , in the episode 's final scene . The song " Don 't Start Me to Talkin ' " , by blues harmonica player Sonny Boy Williamson II , was also featured in the episode .
