Yup, yup to the idea of feel mattering more than lyrics. I've evolved to care more about the lyrics' meaning. And I still have that cassette

I had not listened to that song in full, but as of today I like it, despite not understanding the subject matter. It has Plant's typical musical and lyrical complexity, as usual in dark form. Now and Zen probably is his deepest album, though I haven't listened to any complete Robert Plant album; and I believe it's one of his keyboard-heaviest albums, which increases my enjoyment. If I had to choose my favorite Plant straightforward rock song, however, I'd pick "Hurting Kind (I've Got My Eyes on You)," from Manic Nirvana; it could even be in my Top 10 of such songs from any artist.
I think I have said this in another thread - but Led Zeppelin overrated, Robert Plant underrated.
