Where did I say people engage relatively casually with music? I highlighted a form of engagement that is (a) extremely serious, but (b) actively undermined by novelty.
You're right that a lot of people seem to view lyrics as being at best an annoyance; I've seen multiple people on HN argue with a straight face that in order to translate a song from one language to another language, it's not necessary for the meaning of the new lyrics to be similar to the meaning of the old lyrics.
This is not a sense of "translation" that I'm familiar with for other linguistic phenomena.
I've also seen people take offense at the idea that the concept of a "song" might involve singing.
