I'm surprised you didn't like Double Nickels as much, though I know it can be a little out there for some. I love it so much more for its individual spirit, variety and counterbalancing of themes, both musical and lyrical. You've got a combination of off-beat stream of consciousness songs, the more punk traditional anti-socety songs and the more sincere autobiographical songs. Thinking about it, it's sort of like listening to the band's id, superego and ego respectively. But I digress.
Interesting fact: Double Nickels is only as long as it is because of Zen Arcade. When the release date for Double Nickels changed to the same day as Hüsker Dü's new huge double LP, the Minutemen decided to compete and wrote the entire second half of that album on short notice, haha. That may account for some of the weirder bits, but it wouldn't be quite the same experience without those.
I'm glad to see so much Meat Puppets love. The rest of their material, I'm not so sure about, but that album is just so damn beautiful. I really don't know how else to describe The best albums, in my mind, are ones that can emotionally move me and that album can move me to the other side of the country, far beyond the bounds of my own mind.
As for the rest, I think you covered all of the important (non-metal) releases I wanted to see. The Replacements, The Smiths and Hüsker Dü are among my favorite releases as well. Concerning the Hüsker Dü album, I think it definitely boils down more to an emotional concept. There is no clear story line at all, you've just got to follow the sound and vaguely outlined themes. While nothing is ever clearly understood, though, it makes for a fantastic journey.
1985… That's definitely another important year... for metal... Still, there are some fun releases in the punk and rock areas of music. More Replacements, Sonic Youth and Hüsker Dü. I hope to see your thoughts on the Dead Milkmen's Big Lizard in my Backyard. It's such a fun and quirky punk album and somehow became a huge college radio hit (my station's vinyl copy has a yellow electric tape label with black sharpie proclaiming, boldly, "OVERPLAYED," haha).
