Combination of epic and musicality, coined by DJ MistaJam (Host of the BBC Radio 1xtra show). Often used with a hash tag on twitter or just said on the show to describe the brilliance a song he's playing. Can be used to describe any type of great record, no matter the genre.
This new track MistaJam is playing is PURE #EPICALITY.
