Indeed they do. Though not as popular as the 12 inch 33 1 / 3 rpm format, there is still a considerably strong market for 45 records, especially among record collectors and DJs. Since a record that is played faster is of an inherently higher fidelity, 45 rpm singles are the go to choice for DJs playing music loud over large sound systems, so that no audio quality is lost in the playback process, something that would be exacerbated by the larger forum.
