Green Day's '86' is a punk rock anthem that delves into feelings of ostracism and defiance. The song is from their album 'Insomniac' and captures a sense of betrayal and resilience. The lyrics reflect frontman Billie Joe Armstrong’s experiences with the punk rock community that turned its back on the band for gaining mainstream success. Key themes include alienation, anger, and the struggle for identity. Poignant moments in the song highlight the band's frustration and determination to stay true to themselves despite the backlash.
