Thats pretty elegant, I like it.

Its funny, I've used read heaps of times before, but never thought to use it
to break out of the clunkiness of calling a second script. Thanks!

I quite like:

ls *.mp3|while read mp3file
    whatever_to $mp3file

In fact I even have been known to use that with find to avoid the
syntactic ugliness* of find -name '*.mp3' -exec whatever_to {}\;
And it works well in where the whatever_to is a few lines and you
don't want to write separate script for it when you're doing a slightly
inaccurately named "one liner."

*Personal taste, if you disagree then you are correct, no need to point it 
out.  ;)
