A dj, in order to “play” music needs at least 2 decks or cd’s or turntables. Also, for commercials, must have a mini disk or a tape…
While music is playing our mind thinks when the song will be finished, so before it finished to put another song mixed.
Usually, in most situations, we start the next song and we fade the previous. Then it is time for commercials.
If dj is present then simple plays commercials from a minidisk for example. After commercials music continues….
When any good dj decides to mix a jingle on the music, he tries to not “disturb” the singer.
Like that and better works AIRMIX sound automation in a radio station.
With or without the human presence AIRMIX works perfectly and accurate
