If it's declared with add_columns an accessor is created for it. When you do
a join you should access columns in foreign tables through the relationships.

$cd->artist->name

and similar, rather than trying to force DBIC to bring the artist name in and
doing $cd->get_column('name')

If you use DBIC properly you almost never need get_column.

Generating random methods on the fly is inefficient and can cause subtle bugs.
