The act of identifying an unknown track played in a DJ set.
Definition
"Track ID?" is the question dance music fans most frequently ask after hearing an unfamiliar record in a DJ set. The answer — the track's title and artist — is the track ID. Communities have built elaborate systems for crowdsourcing IDs: 1001Tracklists is a database where users contribute tracklists for major DJ sets and discuss unknown records, Shazam works for many releases, and Discord servers and subreddits host real-time identification threads during livestreams. Some tracks released in DJ sets remain unidentified for months or years (see ID below). For DJs, having tracks that the audience desperately wants to ID — but cannot find on streaming services — is itself a form of distinction.
