Rap music is a part of that lengthy family tree that narrates the tradition and evolution of black music in the United States and that has exerted a substantial influence on music, literature, cinema philosophy, television, commerce, publicity, the media, language, fashion, painting or dance in the last four decades. It is the soundtrack of many activist movements and his lyrics continue to have that heartbreaking and combat component that brings him closer to social criticism. In Spain, for example, the legal proceedings against Pablo Hasél and Valtonyc have placed rap in an unprecedented situation, with the lyrics of their songs constituting crimes.
