D - A - C: Acronym! Not "DACK": Word! Acronyms ARE NOT WORDS and should not be spoken as words. Acronyms are individual letters that represent the initials of corporations, institutions or authorities, alternatively they represent names of scientific, technical or natural phenomena or devices. *Zum beispiel: EMI stands for Electric & Musical Industries, the British-based multinational music giant that owns the Dog & Gramophone trademark, His Master's Voice among its other trademarks(Capitol being one of the lesser trademarks). Under the HMV brand, EMI manufactured a wide range of consumer electronic products like TV sets(colour and monochrome), stereo and mono record players or radio/grams and, surprisingly, whitegoods, like chest freezers and suchlike. EMI also stands for Electro-Magnetic Interference, the noise you hear when listening to AM radio(FM is susceptible but not as much) during an electric storm(lightning strikes) or when someone operates an electric motored hand-tool(saw, drill, etc.) nearby. These represent the ONLY two uses of an acronym. EMI can only be used once for the corporate identity and once for the natural phenomenon just described, its uses are thus exhausted and cannot be used again for either purpose. By the way, *Zum beispiel, is German and means "For example"!

The whole idea of quadraphonic sound was quite ridiculous, really. When you go to a concert tosee, say, the late, great Gene Pitney, for example. He's there on stage, IN FRONT of the audience and his backing band(or perhaps a full-blown orchestra) is behind HIM! So the sound you hear is IN FRONT of you, not around you, unless, that is, the auditorium is echoey, then the sound may bounce around the walls(like the Civic Theatre, Newcastle NSW Australia), which will give a false perception of depth of sound. But if the theatre's acoustics are properly designed, the sound will come only from in front of the audience, as it should. As to CDs, they were first introduced as a play-only medium for public consumption, but as computers developed further, blank 74-minute-capacity CD-R discs became available to burn your own choice of songs onto CD, then came 80-minute-capacity discs, but you could only handwrite any info on their labels with a marker pen, then came CDs with inkjet-printable labels and printers that could print onto those labels, and my creative urges went into OVERDRIVE! Not only could I put the music I WANTED on CD, but I could create a label design to better those commercial-issue CDs. And THEN..... Verbatim started marketing spindle-packs of CD-Rs with SILVER inkjet-printable surfaces.....WOW. These are what I'm using now and they look just BRILLIANT!
