I like Living Loving Maid but I agree that it's the second weakest on the album.
I know people hate Hat's Off and I used to but I kind of like it now.
In the Evening is Decent
All My Love is good but I guess I can see thinking it's annoying.
Down By the Seaside has its appeal but maybe it still belongs on the list (and maybe some of the others I listed do too, there aren't many Zeppelin songs I dislike. Come to think of it Moby Dick is probably the only thing I'd include from the first four albums).
Dyer Maker belongs on this list and is the worst song on the first five albums but it might be amusing schlock if not for the fact that every girl I knew in college said it was her favorite Led Zeppelin song, which just makes me dislike it more. I'm not realizing that despite how much I love Houses of the Holy, it does have the first two non-Moby Dick songs that I'd include on a list like this.
