sometimes there are words which are repeated, this proving that the band is building the songs around the title and the motive of the album itself. notice the <city of glass> in 'ghost of the sun' or <long live the doubt> in 'burn the remembrance' (long live = viva).
there are others too and not only on 'viva emptiness'. i know someone who wasn`t sure that he was hearing 'ghost of the sun' because he thought the track was 'inside the city of glass', judging from the lyrics.
i doubt i made my point, but that`s all i wanted to say.
