Well, the first thing I learned when I did my initial listen: I know lots of Led Zeppelin songs without knowing their titles...and many of those songs are on Houses of the Holy. Sure, I recognized titles such as “Over the Hills and Far Away” and “Dancing Days,” but I hadn't the foggiest idea what songs they were. And then when I listened, I kept having “OH, this is that song!” moments. Such repeat experiences made this seem like a volume 2 greatest hits for Zeppelin; admittedly because most of my familiarity is via the first four albums.
There is an intriguing diversity in song styles. “The Crunge” with its James Brown funk is a particular standout for me. I can see how older fans may have felt a little put off by the experimentation the band does on Houses of the Holy, but I find the shift as interesting.
Songs I Knew I Liked: “The Song Remains the Same,” “The Rain Song,” “Over the Hills and Far Away”, “Dancing Days,” “D'yer Mak'er”, “The Ocean”
Songs I Now Like: Other than identifying unknown Zepp songs I've liked, I can't say there is a new "like".
Songs I Don't Want to Ever Hear Again: None
