I would rather have something like
class MusicList
   sortable_attr_accessor :song, :duration         # does everything
                                          # attr_accessor used to do,  
but
                                          # also defines #sort_by_song,
  					# etc.
end

or
class MusicList
    can_sort_by :song, :duration
end

I guess what I'm saying is I'd rather have explicitly defined  
generated methods than one method that alters it's behavior based on  
its name. Of course these methods  would not prevent you from sorting  
by anythiong else or even still having the method_missing in there, I  
just think it looks cleaner, in this case.
