A non-circular model would be prototype based inheritance. You just 
clone things to subclass them:

Song = Object.new

Song.attr_writer :title
Song.title = 'No title set'

Song.define_method :play
  puts "Playing #{@title}"
end

a_song = Song.clone
a_song.title = 'Song one'
a_song.play

another_song = Song.clone
another_song.title = 'Song two'

subclass_of_a_song = a_song.clone
subclass_of_a_song.play

Then there is no distinction between class/object. This is how 
Javascript does it, and it seems a good solution.

But we have a class based model, not so clean, but acceptable ;-)
