Whilst the previous record was playing the DJ would attempt to find the beginning of the song on the next record. The DJ would place the needle down in approximately the right area then move the record back and forth Cueing on the turntable until the beginning of the song was found. When the previous song completed playing the DJ would introduce the next song and turn the record deck on and the record would quickly whirl up to speed with a characteristic distortion.

It was first used by Edison on his first talking pictures using records for the sound playback. He used the information to synchronize picture and sound. On early soundtrack records the introduction of a "beep tone" was used to tell the projectionist to turn on and off the auditorium speakers so the audience would not hear the projectionist's cue information. Cue tracks were adopted in the early days of Kinascope to cue the film chain engineer and later used in early Ampex Quad Tape systems and is still used today either as voice or digitally for station automation systems. In the early days of bicycled programs cue tracks along with a printed time line was used to inform the engineer of brakes or jam (insert) spots in the tape including a 5 count to the brake in and out locations. Because the program tape or film never stopped. Often the original recording engineer would add comments of his own regarding the program, sometimes humors. When smaller networks that supported independent stations programs, were assembled and the mew track often had the original engineer's voice and the assembling engineer's voice and humor too.

This may also occur when an input is directly patched into an output of the same device, usually due to operator error.
In radio broadcasting, feedback may occur when a DJ increases his or her headphone volume to a high enough level that the microphone is able to pick up the sound coming from the headphones, usually when the DJ's head is turned to one side or another.
