Electronic dance music, also commonly abbreviated as EDM,According to Butler (2006:33) use of the term EDM "has become increasingly common among fans in recent years. During the 1980's, the most common catchall term for EDM was house music, while techno became more prevalent during the first half of the 1990s.As EDM has become more diverse, however, these terms have come to refer to specific genres. Another word, electronica, has been widely used in mainstream journalism since 1997, but most fans view this term with suspicion as a marketing label devised by the music industry". is electronic music that is produced primarily for the purposes of use within a nightclub setting or in an environment that is centered upon dance based entertainment. The music is largely created for use by disc jockeys and is produced with the intention of it being heard in the context of a continuous DJ set; wherein the DJ progresses from one record to the next via a synchronized segue or "mix."
