Three rock songs from the 1970s defied industry expectations to become lasting hits despite substantial obstacles during their development and release. All three faced either repeated label rejections, reluctant artists, or conflicts with misguided marketing strategies, yet their quality ultimately prevailed. These stories demonstrate how artistic persistence and merit can overcome institutional scepticism in the music industry.

Boston's "More Than A Feeling" spent years circulating as a demo before being accepted by a label, having faced multiple rejections. Warren Zevon actively opposed releasing "Werewolves of London" as a single despite its memorable, quirky character, but the label's instincts proved correct. Heart's "Barracuda" succeeded by rejecting their label's bizarre and offensive marketing scheme that sought to exploit an incestuous relationship narrative between the band's sisters, instead allowing the track's musical strength to speak for itself.
