Its the lines like:

musicListStore.AppendValues ("Daft Punk", "Technologic");

in the tutorial

or further down in the tutorial is the better way:

foreach (Song song in songs) {
  musicListStore.AppendValues (song);

where your store contains objects rather than columnar values.  The
downside of that is that you have make and attach render functions for
each column.

artistColumn.SetCellDataFunc (artistNameCell, new Gtk.TreeCellDataFunc

That works really well and gives you mucho flexibility/control but gets
pretty tedious and results in lots of 'plumbing code'.

That is the upside of the Hyena
<http://www.mail-archive.com/gtk-sharp-list@lists.ximian.com/msg03669.html> approach,  a column can be directly attached to an object property.

new Column ("Pears", new ColumnCellText ("C", true), 1),

 - the literal property "C" of the object in the store, via reflection,
is mapped to the column "Pears".
