A nightclub (also known as a discothèque, or simply a club or disco) is an entertainment venue which usually operates late into the night. A nightclub is generally distinguished from bars, pubs or taverns by the inclusion of a dance floor and a DJ booth, where a DJ plays recorded electronic dance music, disco, hip hop, R&B, rock music, reggae, and pop music.
The music in nightclubs is either live bands or, more commonly, a mix of songs played by a DJ through a powerful PA system. Most clubs or club nights cater to certain music genres, such as techno, house music, trance, heavy metal, garage, hip hop, salsa, dancehall, drum and bass, dubstep or soca music. Many clubs also promote playing the Top 40 which has most of the night playing the most broadcast songs of the previous week. .
