I Need to Know (Tom Petty and the Heartbreakers song)

"I Need to Know" is a song written by Tom Petty and recorded by American rock band Tom Petty and the Heartbreakers. It was released in 1978 as the first single from their second album You're Gonna Get It!. It peaked at #41 on the Billboard Hot 100 singles chart in 1978. This song as well as "Listen to Her Heart" was already being played live in concert as early as June 14, 1977, as is evidenced in a performance on Germany's music television show "Rockpalast".

Cash Box said that it is "hard driving rock 'n' roll" and that "the hook repeats hypnotically as the guitars drive the message home." Record World called it an "energetic rocker."
