a Jamaican-breed idea which involves remodeling and changing existing elements of a song. Mainly through adding effects such as echo, delay, flange, phase, noise gate etc. to it, and in most cases – removing vocal samples. Also the engineer often creatively drops different instruments in and out of the mix at different times. When this is done well, it's an art form of its own.

a style and a genre of electronic music sounding and structured similarly to reggea but in most cases “stripped off” of lyrics and harmonies. Instead, a massive bassline is often introduced. There is a multitude of sub-genres within dub like dub house, ambient dub or techno dub. All of them do (or, at least, did) resemble more or less their Jamaican prototype.
