“Wonderwall” by Oasis, released in 1995, became the defining anthem of ‘90s Britpop and the unofficial soundtrack to dorm room guitar jams everywhere. Written by Noel Gallagher and described as a song about “an imaginary friend who’s gonna come and save you from yourself,” it captured a generation’s yearning in under four chords. Topping charts in Australia and New Zealand and going octuple platinum in the UK, it remains Oasis’ most iconic track — and probably the most requested song at open mic nights ever since.
