I usually go first with my explorer folder and labelled them “NEW MUSICAAA Sept 2013”, and then labelled them on the sub-folder based on their genre,
When its time for the gigs, i rearrange them back in My Serato Playlist, like “KICK A$$ Gig, Sept 27 2013 @ Titty Twister Club, Mexico City”, and then make another sub-folder under that, and labelled them sometimes as “BEGINNING”, “MIDDLE, “END”, “Pumpin'” , “Booty Shakin’ Anthem”, or can just labeled them by its genre “FUNKOT”, “DUCTH”, “BREAKDUTCH”, “PROG” and so on
