I love the way in which you can listen to a song for its for its flow and appreciate it, then listen to it again and pick up on the more subtle metaphors and word play.
A real interesting read so far [haven't read it all yet...], It'd like to see how a number people interpret the same HipHop lyrics too. Actually, I also think It'd be incedibly interesting to see what different images feelings people get form instrumental music too, I guess they'd vary a lot more.
