Many aspects of the British Wizarding World have Muggle equivalents. For example, after reaching age of 17 wizards can be licensed to apparate, while Muggles can learn and be licensed to drive cars. In the fifth and seventh years of Hogwarts or Muggle secondary school, external examinations take place. Some aspects of Muggle pop culture are also mirrored in the Wizarding World such as rock music, posters, and tabloids. A few young wizards embrace Muggle culture whole-heartedly: as a teenager, Sirius Black filled his room with pictures of Muggle pin-up girls, motorcycles and rock bands in rebellion against his prejudiced, Muggle-hating parents. Muggle music is heard in the film adaptation of "Harry Potter and the Order of the Phoenix" - music by The Ordinary Boys is heard playing in the background of the Gryffindor common room.
