Yup, Murray, I did think about making an everyday use copy. I used the originals only once, to make my copies. Still, prerecorded cassettes are often made on cheap tapes, and they tend to bleed through from one layer of tape to the next, and develop squawks in the mechanism.
But then, after I got well along in my collection of CD's, I learned that CD's tend to lose their information after 15-20 years. Maybe the vinyl enthusiasts were right after all.
