@David Duarte A friend organises her playlists by the hour, building energy over a four hour nightclub set, hour one warms up, hour four headlines. She can play for hours with this system and is a great Dj. Another sorts his tracks by the month he bought them, and that works for him. I’m more chaotic. I usually throw together playlists of up to 100 tracks, nailing the first 10–20 in a sequence I know works so I can fall back on it if inspiration fades. Over time, I find tracks by remembering the gigs I played them at and digging through playlists in Rekordbox. Sometimes I “lose” tracks, only to rediscover them later while cobbling together a new mix. I did try organising by key for a year but my mixes became flat and formulaic.
