Basically agreed on Faust IV, though I think I have more tolerance for the noisy bullshit.
Metamorphosis is pretty enjoyable if not super necessary. I like "Downtown Suzie," dumb vocals and all, and "If You Let Me" is cute. The Performance soundtrack version of "Memo From Turner" is way better. Have you heard Vashti Bunyan's version of "Some Things Just Stick in Your Mind" from when she was trying to be a pop singer? Pretty good imo.
