"Born to Be Wild" is a song written by Mars Bonfire and first performed by the band Steppenwolf. Although the lyrics do not specifically mention motorcycles, the song is often invoked in both popular and counter culture to denote a biker appearance or attitude since being featured in the 1969 film Easy Rider. Sometimes, "Born to Be Wild" is described as the first heavy metal song, and the second-verse lyric "heavy metal thunder" marks the first use of this term in rock music (although not as a description of a musical style but rather a motorcycle).

The Pusher" is a rock song written by Hoyt Axton, made popular by the 1969 movie Easy Rider which used Steppenwolf's version to accompany the opening scenes showing drug trafficking. The lyrics of the song distinguish between a dealer in drugs such as marijuana—who "will sell you lots of sweet dreams"—and a pusher of hard drugs such as heroin—a "monster" who does not care "if you live or if you die". Steppenwolf version The song was made popular when rock band Steppenwolf released the song on their 1968 album Steppenwolf. Organist Goldy McJohn, who recorded the original Steppenwolf version, said the version that appears on Early Steppenwolf performed by The Sparrows, a predecessor band to Steppenwolf in 1967 at the Matrix came about when singer John Kay and Jerry Edmonton were late for a performance: Nick and Mars and me started that long version of the Pusher. John and Jerry's flight was late one night at the Avalon Ballroom, so we started and then we perfected it at the "Arc" in Sausalito on New Year's Eve in 1966.
