Thanks Guy for your speedy response :)  I had somewhat the same idea
when I was on my way home earlier, and it works perfectly :)

But I have an additional question: how can I type that command so that
it will re-encode all the mp3's in the folder?  One time, when I tried
using wild cards in coverting multiple mp3's into multiple wav's, I
ended up with one 400+ meagabyte wav file, not multiple wav files.  I do
need to add, though, that the 400+ megabyte wav file was perfectly
usable, just, ahem, not very convenient to find songs in :) By copying
and pasting I can make a REALLY long shell script to do the job, but I
figure there has to be an easier way...

Thanks again for your help :)
