Changer Life refers to the length of time
that a CD stays in a multiple-disc changer
without getting removed and put back into its sleeve. I’ve got
a 5-disc changer, and I don’t usually fill it up unless I’m
backlogged. Lately I’m backlogged a lot, though, and I find myself
frequently removing five discs and replacing them with five more.
I feel a slight twinge of dread when I do this, though, since the
sheer volume of CDs in the house means that there’s a good chance
that the five just-reshelved CDs, regardless of their quality, have
just enjoyed their final sojourn in the land of the pertinent. Consequently,
when the changer’s full and I’m putting something new into
it, the more interesting CDs already in it stand a better chance of
not getting pulled than do the lesser lights. I doubt that it’ll
clarify anything, but we non-mathematical types have equation-envy
real bad, so let me try to render it as a formula:
where x = any given CD
and
y = interest value of any as-yet-unplayed CDs on, near, by or within
reach of the stereo,
Changer Life = (Quality of x) - y
