A plain-text metadata file that stores the track listing and start times for a continuous audio recording such as a DJ mix.
A CUE sheet (file extension .cue) is a plain-text file that maps chapter markers, track titles, artists, and start times onto a single continuous audio file such as a DJ mix or album. Media players and CD burning software read the CUE sheet alongside the audio file to allow listeners to skip between individual tracks within the recording.
Why it matters
When a DJ releases a recorded mix as one continuous audio file, a CUE sheet lets listeners navigate to specific tracks without the DJ having to split the recording into separate files. It also provides the structured metadata (artist, title, start time) that DJ mix hosting platforms and CD creation tools require to display a proper tracklist.
In practice
Most CUE sheets are created manually in a text editor or automatically by DJ recording software. Each TRACK entry specifies an INDEX 01 timestamp in MM:SS:FF format (minutes, seconds, frames at 75 frames per second). Pair the .cue file with the audio file and keep both in the same folder so players can locate the recording.
