They were probably my most favorite band for a very long time before I started exploring metal. I recently found a used copy of SOMMS in a little music store, so I got to a wish I've had for about 5 or 6 years now.
Unlike you, HarmonyDies, Down on the Upside was probably my least favorite of all their albums. Badmotorfinger and Superunknown were the ones I thought to be the best not only overall, but that have the lion's share of the best songs as well. "Holy Water," "Limo Wreck," "Jesus Christ Pose," "Fresh Tendrils," "Like Suicide," all were my most favorite songs... then on UMO.K. There was also that cool 665 song where if you play it backwards, he's singing "Hail Santa, my Christmas King!" and who could forget "Beyond the Wheel"?
*Sigh...* Good memories.
