Music is a powerful tool that can provide the perfect outlet for opinions, emotions, world views and even epitomise the political climate. Some of the biggest social and political movements hold a music moment behind them, from Frankie Goes to Hollywood’s ‘Two Tribes’ fight against nuclear war, to Morrissey’s impassioned plea against the slaughter of animals in ‘Meat is Murder’, to Gwen Stefani’s remarks on sexism and stereotyping of the male-dominated music industry in ‘Just a Girl’.
