I was thinking particularly about lyrical polemics Leveller. I'm not suggesting overtly political songs can't be great art, just that they so rarely are. Religious songs can fall prey to the same impulse of wanting to hammer home a message but using lyrics as a way of sugaring the pill, which is why I prefer, say, 397 from the Denson Book "There is a fountain filled with blood, drawn from Immanuel's veins: And sinners plunged beneath that flood, Lose all their guilty stains" to "Lord of the Dance".

If there's to be a pill I prefer it bitter than hidden in sugary analogies. Modern political songs tend to be too keen on allusion for my simple tastes.
