https://www.youtube.com/watch?v=NUTGr5t3MoY Basket Case is archetypal Green Day. It contains all their calling cards - nervy palm muting, a euphoric bassline, machine-gun drum fills - and wraps them all up in a neat, paranoid package. Written about Billie Joe's struggles with anxiety, it remains the classic example of a brilliant pop punk song. Best Bit: The whole track is a little masterpiece from start to finish, but the instrumental section before the final chorus truly kicks it into overdrive.
