Tower is a song about iconism, and people being supposedly "above" you, it uses the imagery of a tower to say that they've built the tower themselves. If you imagine the fanciful city of migar in FFVII while reading this song it may help......
TOWER
Verse I
Place yourself above me,
High in your castle,
Your tears are my rain,
Come here,
Bring yourself,
And show why,
Why u live above me,
Can I ever find my sanity in u?
Verse II
For you’re so great,
Will you ever come down from your great city?
Just for me?
Corrupting innocent souls,
A torrent of angels now free,
U can’t bring redemption,
Only fear
Chorus
Soar up,
I Cant see your tower for the clouds,
Rise above all,
How could u find your equal here?
Transcending boundaries,
How dare I think I could be u?
Does money buy justice?
Does fear gain love?
Verse III
Walls and walls of stone,
Unassailable heights,
No way up to that heaven of you,
Honoring false idols,
How could a person be a god?
Yet u try,
Creation of an icon
How ever false it may be,
Via lies, two faced ways and crimes
