That was another "forget to remove idle callback when finalised" bug,
it's fixed now.

It might be worth asking if there is a compressed version of the .xml
file available too, for example a gzipped version is ~270kb instead of
5.8Mb - and that would save a lot of bandwidth. If there is anything he
needs to know about Rhythmbox which you don't feel up to answering, feel
free to pass my address on.

On a related note, we can probably do some other things to reduce the
bandwidth. The most obvious would be caching the xml file as
~/.gnome2/rhythmbox/magnatune/song_info.xml (or whatever) and only
downloading it every now and then, and in the background. We could
probably send the HTTP magic needed to get the "it hasn't changed"
response, so we know not to update.

Rhythmbox supports attaching extra data, but it's not currently exposed
to Python.

One method of doing it (which would be fairly simple) would be to give
each entry a dictionary, accessable via "" or something - how
does that sound?
