I'd like to reawaken this thread - being on "neutral" territory may be an advantage for us all here.
For the moment it would be interesting to pursue the avenue of "political music that challenges the status quo" rather than get too bogged down in issues such as if/why all music is political and so on.
What could be more neutral than first exploring whether and how any music, that with words and that without, can be intended and/or regarded as political?
Along 'the avenue of "political music that challenges the status quo" ', presumably one finds more examples, similar in intent, context and construction, to this? After we will have gone along that avenue for a bit, what would turn its features from a mere catalogue to an assessment? Wouldn't we otherwise get bogged down in cataloguing?
