Comments should say what the function is supposed to do, not how it
does it. If this quickly disagrees with the function, then we have an
API thats quickly changing and hello regression city! Which really I
don't think is the case: Amarok's fast development might hide the fact
that there's plenty of stuff that doesn't get touched much at all
(which is good).

So anyways I really do hope that we can get everyone on board with
commenting code as we go along.

On a related note, I'm going to be at-some-point over-commenting the
DAAP client and server code, for the purposes of my computer science
capstone project. I will be ignoring my own advice about comments
