"For What It's Worth (Stop, Hey What's That Sound)" (often referred to as simply "For What It's Worth") is a song written by Stephen Stills. Performed by Buffalo Springfield, it was recorded on December 5, 1966, released as a single on Atco Records in December 1966 and peaked at No. 7 on the Billboard Hot 100 chart in the spring of 1967. Its association with the Vietnam War is a popular misconception; the song is about young people clashing with police during the counterculture era.
