“Microphone Fiend” was the second single released from Eric B. & Rakim‘s second album Follow the Leader.

The song became something of a signature song for rapper Rakim, and AllMusic’s Steve Huey says the song “weaves references to substance addiction throughout in explaining why Rakim can’t keep away from the mic.” Featuring a prominent sample of Average White Band’s 1975 hit “School Boy Crush”, the song was further evidence of Eric B.’s fondness for soul samples.
