Survivor's rugged yet plucky spirit was summed up by their 1982 track “Eye of the Tiger,” a pugilistic rocker with an era-defining riff; its use as the theme song of the boxing blockbuster Rocky III propelled the band to early-MTV ubiquity. Punchy anthems like the harmony-rich “I Can't Hold Back” and the sparkling “High on You” showed how Survivor's resolve extended to the romantic arena, while lighter-worthy ballads like the slow-burning “The Search Is Over” and the wistfully nostalgic “Summer Nights” super-sized rock's love-song ideal through grand hooks and yearning lyrics.
