The song isn't a war song, it's a song for society. Entropy, as quoted, referrs both to chaos and to "a process of degradation or running down or a trend to disorder". The passage quoted by Higurashi is best applied when added to the subsequent statement, 'scream to the tune of the backgroud noise'. References to social decay, a disillusion with society, run throughout the song. Lines such as those mentioned and the image of a person self-inflicting pain reference to a system in which people are publicly happy but privately miserable, where material and externality have replaced the content of one's actions, and where order and values are degrading into , well, entropy.
