Floor filler
A floor filler is a record that reliably brings people to the dancefloor. It is defined by what it does in a room rather than by anything in the music, so it is one venue’s and not another’s.
In practice
Defined by what it does in a room, not by what is in it. And it only works because of what surrounds it.
Carry a handful you genuinely trust for the room you are playing, and place them where the energy actually needs them rather than where you want to hear them. Two or three across a two-hour set is more than most people think and considerably fewer than most people play. Keep a note of what worked where — the same record in a different venue is a different record, and a personal list beats any published one.

Where these come from: Set-building practice. The measured shape of real sets built on Mixgraph is published on the energy curve page. For what we can measure, see the measured shape of a set.
Why it matters
The trap is treating it as a property of the record. A track that fills the floor at a big room at midnight can empty a small bar at ten, and DJs who learn a list of "anthems" rather than a sense of what a specific room responds to get caught out constantly.
The second trap is spending them. A set built entirely from floor fillers has no shape, because every record is competing with the one before it and nothing has room to build. They work because of what surrounds them, which is an argument for the records that are not.
Frequently asked
How many floor fillers should a set have?+
Two or three in a couple of hours, placed where the energy needs them. A set made entirely of them has no shape, because nothing has room to build.
Is a floor filler the same everywhere?+
No — it is defined by what a room does, and rooms differ enormously. A track that works at midnight in a big room can empty a small bar at ten.
How do I find them?+
By keeping notes on what actually worked, venue by venue. Published lists describe somebody else’s rooms.

Energy curve
An energy curve is the shape a set makes over time — where it starts, how steeply it climbs, where it peaks. It is the plan behind a running order, and the thing a crowd feels without being able to name.
Peak time
Peak time is the stretch of a night a set is built toward — the busiest hour, and the point of highest energy. It names a position in a night rather than a specific sound.
Secret weapon
A secret weapon is a record that works as reliably as an anthem but that almost nobody else is playing — an old B-side, an unreleased edit, something from a scene the room does not follow.
Track selection
Track selection is choosing what to play and in what order — the decisions rather than the mixing. It is what separates two DJs with identical technical ability and identical libraries.
