There's a tier of Melvins covers by which I judge all the others. Green Manalishi, Sacrifice, Lexicon Devil, Youth of America, Jerkin Krokus.
The next tier has most of Sausages, HAT B Sides, PAT, Crybaby, Kiss covers, Flipper covers, etc.
Then there's this one and a few other classic rock and novelty tunes that really don't do much for me. Oh well.
