Subject: Listing an Array created within a Class

I am learning from Programming Ruby wich comes with Ruby instalation.
In the chapter about containers - Implementing a SongList Container
I took the code in NetBeans like follows:

require 'Baza.rb' #here is my Song class
class SongList < Song
  def initialize
    @songs = Array.new
  end
end

class SongList
  def append(aSong)
    @songs.push(aSong)
    self
  end
end

list = SongList.new
list.
  append(Song.new('title1', 'artist1', 1)).
  append(Song.new('title2', 'artist2', 2)).
  append(Song.new('title3', 'artist3', 3)).
  append(Song.new('title4', 'artist4', 4))

############# Here is my problem
puts list.to_a ?????????
What line must I have here to have at terminal the array that is created
in the SongList like this:
Song: title1--artist1 (1)
Song: title2--artist2 (2).... etc , so that I can work with it?
and/or to see the list elements with list[0, 2]
Thanks
