My new favorite internet time waster is the 120 Minutes Playlist Archives. Beware, because it's very easy to spend hours alternating between it & YouTube in search of all of those Mudhoney & Dinosaur Jr. videos you never knew you couldn't live without. Three gems I found:
Brainiac - "Vincent Come On Down"
Sebadoh - "Rebound"
Husker Du - "Makes No Sense At All" (BOW DOWN TO GREG NORTON'S MUSTACHE!)
