This test was performed at the start of Parking Lot and Boom-Box Experiments to prepare the participants and make sure that all the equipment were operating properly. Each cassette would announce which tape number it was, much like the way the Zaireeka discs announce which disc they are when playing the album on four CD players. "The test begins now" phrase was later reprised to open "Fight Test" and the Yoshimi Battles The Pink Robots album.
