I need one song that relates to power and has figurative language in it.

I went with the idea that music is a form of poetry, and
coupled with the use of figurative language, moved this question to the "Poetry" group. 
In reflecting on this, I would use a song from U2 that talks about the abuse of power. 
Off of their album, "The Joshua Tree," check out the track, "Mothers of the
Disappeared."  While there are different interpretations of it, the song is about
mothers whose children were kidnapped in South and Central America.  The song has
chilling references to the Dirty War in Argentina, where state sponsored terrorism
resulted in the abduction of thousands of children, such as students, journalists, or
any young person who spoke out against the government.  Similar practices in El Salvador
prompted the group to write the song.  Steeped in the voices of those who suffered from
the abuse of power, pay attention to examples of imagery such as, "Cut down and taken
from us" or the description of how the night "hangs like a prisoner," a deliberate
example to highlight governmental abuse of power.  The entire song of mourning and the
mood created within it help to bring to light how power and its abuse can create
profoundly sad and painful conditions on citizens.
