Hi Allen,

You need to define an initialize method which can take the arguments
you are passing to "new." For example:

class Song
  def initialize(name, artist, duration)
    @name, @artist, @duration = name, artist, duration
  end
end

I'm not sure if that is an oversight in the book, or if maybe the
initialize was introduced earlier and you forgot to include it.

Also you will need a "puts" before song.to_s if you expect to see any output.
