Jungle Music is a style of electronic dance music that grew from Hardcore Breakbeat and its precursor Acid House in the UK around 1992 with heavy influences from Ragga, Reggae and Hip-Hop. Running at around 160 to 170bpm, its dominant feature is a heavy bass and complex, chopped up and recycled breakbeats. The term is generally used interchangeably with drum and bass, although this second term appeared later. However, it is also argued that jungle can be differentiated to modern drum and bass through the overall song structure: drum and bass has an integrated percussion and bass structure while jungle has a distinct bass line separated from the percussion. Also, many people feel that the general 2-step beat of drum and bass is different from its predecessor's more complex "chopped" breakbeats.
