This code should be after this:

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

You probably thought that the code you chose to execute was
independent of the code above it. In Ruby, classes are open and new
methods can be added to a class by using the 'class' keyword again and
again :)
