One idea would be to have the entry view hidden until it has been
downloaded at least once, and have some kind of "MagnaTune intro"
displayed instead.

Displaying an empty track list probably isn't useful, so maybe we could
have something displayed instead which said what MagnaTune was, a
download progress indicator, and a "continue to track list" button
(which would only be enabled once the download had finished).

For Python plugins, it's easier to embed the GtkUIManager XML directly
into the .py file, see plugins/pythonconsole/ for an
example of how to do it. You'd probably want something like the
following (which I've based on BrowserSourceViewPopup)

  <popup name="BrowserSourceViewPopup">
    <menuitem name="AddToQueueLibraryPopup" action="AddToQueue"/>
    <menuitem name="MagnatunePurchaseTrack" action="MagnatunePurchase"/>
    <menuitem name="BrowseGenreLibraryPopup"
    <menuitem name="BrowseArtistLibraryPopup"
    <menuitem name="BrowseAlbumLibraryPopup"
    <menuitem name="PropertiesLibraryPopup" action="MusicProperties"/>

The "MagnatunePurchase" action would get the list of selected tracks
from the entry view, and then do the purchasing stuff.

The int is the 0 that you passed to connect_object(), and the boolean is
"over_entry" which indicates whether the context menu is for an entry,
or a click in "empty space". Basically if it's false you pop up the same
menu you would for the impl_show_popup virtual function, and if it's
true you pop up the "track context menu".
