"ID" means nobody has named the track. Most of the time it hasn't been released yet, or the DJ is keeping it quiet. "ID - ID" is the full shrug: no artist and no title.
You'll see it all over tracklists from festival and club sets, and it's usually stuck to the one track everybody wanted to know about.
The shorthand, decoded
- ID - ID: artist and title both unknown.
- Artist - ID: you know who made it, not what it's called. Often a new track the artist is testing on a crowd before release.
- ID Remix or ID Edit: the original song is known, but this version isn't out.
- w/ (with): two tracks playing at the same time, mixed together.
- Edit or bootleg: the DJ's own version of a track. Plenty of these never get released.
Why no app can name an ID
Shazam and every other song-ID app, Chord included, work by comparing what they hear with recordings they already have. A track that hasn't come out isn't in anyone's catalogue, so there's nothing to compare it with. A cleaner clip won't change that.
Finding it later
Hold on to your clip and remember roughly when in the set it played. Fans keep editing 1001Tracklists after a show, and IDs get filled in once the track comes out. A lot of DJs answer "ID?" comments, or post the name when it's released. Reddit threads and community groups for the genre are worth asking too.
Keep the clip
In Chord, a clip with no song still sits in its Night. When the track finally comes out you can add it to the clip, and you'll have the moment you heard it first.

Questions people ask
What does ID mean in a DJ set?
ID means the track hasn't been named. It's usually unreleased, or the DJ hasn't said what it is.
What does w/ mean in a tracklist?
w/ means "with". The DJ played two tracks at the same time, mixed together.
Can any app identify an unreleased track?
No. Song-ID apps match recordings they already know, and an unreleased track isn't in any catalogue yet.
