Track ID
トラックID
The act of identifying an unknown track played in a DJ set.
Definition
"Track ID?" is the question dance-music fans most frequently ask — both at the venue and afterwards online — when an unfamiliar record appears in a DJ set, a livestream, or a published mix. The answer — the track's title, artist, and ideally label or release status — is the track ID. The phrase has become standalone slang in the community: a YouTube comment that simply reads "0:43 — track id?" is instantly understood by anyone reading it, and entire subforums and Discord servers exist for nothing else. Note the distinction from the closely related glossary entry "ID (Unreleased Track)" — that entry covers the placeholder for tracks that cannot yet be named; this entry covers the act of trying to name them.
Communities have built elaborate infrastructure for crowdsourcing track identification. 1001Tracklists is the central global database: users transcribe tracklists from major DJ sets, festivals, radio broadcasts, and livestreams, mark unknown moments as "ID," and discuss them in attached forums until someone identifies the record. MixesDB performs a similar role with a wiki-style structure and a particular strength on older sets. TrackSniff and other newer audio-recognition tools attempt to automate identification from short clips. Shazam — the consumer audio-fingerprint app — works well for finished commercial releases and is often the first thing a listener tries, but it has a structural limitation: tracks that are still unreleased ("ID" placeholders) are not in Shazam's fingerprint database by definition, so the most-wanted IDs in any given set are precisely the ones Shazam cannot solve.
Beyond the databases, real-time identification happens in Discord servers, subreddits, and Facebook groups that follow major broadcasts. During an ASOT, Group Therapy, or Future Sound of Egypt episode, listeners post short clips of unknown tracks within seconds of them airing; community members with broader libraries, label connections, or simply better recognition memory call out IDs across the broadcast. Some IDs are solved within minutes; others persist for months or years and acquire near-folkloric status as long-unsolved tracks fans return to whenever a new clip surfaces.
For DJs, carrying tracks the audience desperately wants to ID — but cannot find anywhere on streaming services — is itself a form of distinction. The DJ who routinely plays exclusive promos from in-demand producers signals industry access that ordinary subscription music libraries cannot replicate, and the resulting "what was that?" reaction from the floor is part of the value of the set. Conversely, for producers, a buzz-generating ID rotation across multiple top-tier DJs is one of the most reliable signals that a track is going to land at retail.
