yeah well, so did i. but in retrospect, for a random playlist of
albums for a custom script to be used with mpg123, permutations make
more sense.
but i still do

mailman is written in python, right? from my experience, python

i don't know how python and shell interact - since i plan to

Hmm, here's a really quick & dirty hack:
$ cat data.txt
foo
bar
baz

$ randline data.txt
quux
$ randline da
13 matches
