Megamix is a term generally used in the music industry for a non stop mix of many tracks, usually created by a DJ. Examples of megamixes can be found more often than not nowadays in the form of many dance albums by the Ministry of Sound 'Annual' albums and similar. Other good example of a 'megamix' are the 'Grandmix' series CDs created by Dutch DJ Ben Liebrand, or the megamixes played during the ID&T events Sensation
