Oi! Music is a subgenre of punk rock that originated in the late 1970s in the United Kingdom. It is characterized by its straightforward, anthemic sound and often features lyrics that address working-class issues, social struggles, and a sense of community. The genre is closely associated with the Oi! movement, which sought to create a distinct identity for the working-class youth. The term "Oi!" itself is a call to attention, often used in songs to engage listeners. Notable bands in the Oi! Music scene include Cockney Rejects, Sham 69, and The Business. The genre has influenced various other music styles and continues to have a dedicated following today.
