Romania is a European country whose population consists mainly (approx. 90%) of ethnic Romanians, as well as a variety of minorities such as German, Hungarian and Roma (Gypsy) populations. This has resulted in a multicultural environment which includes active ethnic music scenes. Romania also has thriving scenes in the fields of pop music, hip hop, heavy metal and rock and roll. During the first decade of the 21st century some Europop groups, such as Morandi, Akcent, and Yarabi, achieved success abroad. Traditional Romanian folk music remains popular, and some folk musicians have come to national (and even international) fame.
