Feel & analysis
Acousticness
Acousticness describes how much of a record was played rather than programmed — a piano, a guitar, strings, a voice in a room. In a club catalog it is rare, and the rare ones are unusually useful.
In practice
The one record in the bag that sounds like nothing else in it. Worth carrying two or three for exactly that.
Keep a handful and use them where contrast does more than energy — an opener, a bridge between two genres, the moment after a peak when the room needs air rather than another big record. They layer well over straight grooves for the same reason: a played instrument rarely fights a programmed one for frequency space. Check the tempo behaviour before you rely on one, though, since anything genuinely played may not hold a fixed grid.

Where these come from: How acoustic records behave in a club set — practice, not a setting. Where software scores this, the numbers are blunt: across our own 445,032 analysed tracks only 0.10% read above the halfway mark, which is correct for electronic music and not a way to sort a library. Finding these is a listening job. For what we can measure, see the related question of played versus programmed.
Why it matters
An acoustic record is the one thing in a bag that sounds like nothing else in it. That makes it disproportionately valuable at the two moments a set needs contrast most: an opening hour that has to feel like a room filling rather than a night starting, and the point after a peak where you need to change the air without dropping the tempo.
It is also the safest kind of record to layer, because acoustic instruments rarely occupy the same frequency space as a synth bassline and a 909. A piano loop over a rolling groove sits in a gap that most electronic records leave completely empty.
Frequently asked
Why are acoustic records useful in a club set?+
Contrast. They sound like nothing else in the bag, which makes them valuable as openers, as bridges between genres, and at the point after a peak where the room needs air rather than another big track.
Do acoustic tracks layer well?+
Unusually well. A played instrument rarely occupies the same frequency space as a synth bassline, so a piano loop sits in a gap most electronic records leave empty.
Is acousticness the same as unplugged?+
Roughly the intent, but it describes the sound rather than how the record was made. A heavily processed acoustic recording can read as electronic and vice versa.

Liveness
Liveness describes whether a recording was made in front of an audience — a live set, a concert cut, a room recording. Some software scores it automatically; either way it tells you a track will behave differently.
Speechiness
Speechiness estimates how much of a track is talking rather than music — a skit, an intro monologue, a podcast. It is not a vocal detector, and mistaking it for one is a very common waste of an evening.
DJ tool
A DJ tool is a track built for mixing rather than listening — long, loopable, mostly percussive, with little melody or arrangement. It exists to bridge, extend and hold, not to be the record anyone remembers.
Warmth
Warmth is body in the low-mids — the part of a record that makes it feel round rather than thin. It is what people mean when they call a track analogue, and it has nothing to do with the equipment.
