Field notes
A tag can include an optional style, such as DNB.LIQ, which the page says users can leave off when uncertain. Energy runs from E1 to E5 relative to a track’s own genre, and the page distinguishes it from Mixed In Key’s 1–10 intensity scale. Its app table marks Rekordbox as checked; Engine DJ, Traktor, VirtualDJ and djay are listed as not yet checked.
