You can also do:

   attr_accessor :name, :duration

There's no point having that, if you've already got a writeable
'duration' attribute :-)  Actually one of the nice things about the
attr_*-style technique is that you don't have to have methods with
'set' and 'get' in their names.  Instead, you just do:

   class Song
     attr_accessor :duration
   #...
   end

   s = Song.new
   s.duration = 180
