Don't use class instance variable example. Use a factory methods example.

This could be Album#search or some such that returns an array of Album instances which match a title for artist search.

@gaand By this, did you mean not to every use class instance variables, or to only use them for factory methods?

I ask because #20 brings it up, and the linter (and the community) prefer class instance variables to class variables.
