 This line end the definition of the class SongList

   ^^^
 now, ruby has a problem because it find `end' which match nothing

D> def deleteFirst
D>     @songs.shift
D>   end
D>   def deleteLast
D>     @songs.pop
D>   end
D> end
   ^^^

 same here

 remove the first `end' which close the class SongList

D> list = SongList.new
D> list.
D> append(Song.new('title1', 'artist1', 1))
                                           ^
                                           |

 a `.' is missing at the end of the line

D> append(Song.new('title2', 'artist2', 2)).
D> append(Song.new('title3', 'artist3', 3)).
D> append(Song.new('title4', 'artist4', 4))
