The songs I am presenting now to you are not arranged in a strict value hierarchy, it would be a difficult job to do such a thing objectively. I instead took a series of factors into consideration like the attitude, the depth of the lyrics, the history of the band/artist regarding such themes, success to the public and overall artistic impression.
Regarding the attitude we will find songs that are either active or passive. We will also hear songs that try to show us hidden truths by addressing our intellect or songs that try to reach our emotional segment and so to get an emotional response. As themes we will discover the "mechanization of man" which I coincidently also addressed in some of my poems, greed and money, abuse of power, control and surveillance.
