Topic: CD Terminology

	Neil Forbes Rock, Country or R. & B. - Classic Hits for me! Member since Dec 2014 252 Points	I suggested the term "CD Sampler" because the standard diameter CD disc is under-utilised, the maximum playing capacity is 80 minutes yet many of these discs only run for up to 20 minutes(a full hour's capacity gone to waste), plus the number of tracks, sometimes 3, sometimes more and sometimes less, plus variants of the same song(or tune). The 45rpm format, by comparison, is a no-waste carrier which can hold up to 7-and-a-half minutes per side(if cut at EP pitch) in full stereo. The fact that there's only one song(or tune) to a side is what defines it as a single because, when on a turntable, one side is exposed to the pickup whilst the other is face-down on the turntable mat. With the CD "sampler", all content is accessed by the laser pickup(yes, only one track is played at a time - but that's not the point), as against the 45-single where just one track is available to play. Thus, the term "single" is applicable to vinyl 45s only. The term "album" can apply to any music collection, be it LP, cassette or CD.
