I too like Blow up your video, though mainly because of 'Two's up' one of my most favourite DC songs. blows me away everytime.
love 'In through the out door' tho i never thought of it as unpopular before.
Probably unpopular through many Zep fans but I agree that album is enjoyable.
Albums like Never Say Die while I still from an objective stance think its a poor album it is one that kind of grew on me a bit.
Metallica Load and Reload have grown on me a lot actually because back in the day I judged them too often compared to their earlier classics but as blues rock type albums they actually pack some real underrated gems on them such as King Nothing, Unforgiven II, Better Than You, Fixxxer, Until it Sleeps, Mama Said, Fuel, Carpe Diem baby, Bleeding Me. I don't like The Memory Remains or Low Man's Lyric at all though.
