Re: 8-tracks

I bought a Ravi Shankar 8 cartridge in '69, and I always marvelled at the 
observation that no matter how many times I hit the track change button, the 
music sounded exactly the same; no change in tone, melody, or volume, or 
quality, for that matter;  forty five minutes of the same three out-of-tune 
notes droning on and on. Who could concentrate on raching nirvana listening 
to that???   Mark Childers
