I've really lost it this time

Every couple of months I hear a tune that I become obsessed with. I play it many times a day for a few days. Normally it’s some crunchy electronics with a synth hook that just catches me emotionally for some reason (e.g. Plaid’s Bo Bootch or Aphex’s Laughable Butane Bob). This time it’s Dokaka’s cover of Metallica’s Creeping Death.

Why is this insane? Dokaka are an Otaku A Cappella act. One guy, he covers tracks by paintakingly imitating each instrument layer of the original track and mixing the lot together to form a really dense but highly nonsensical sound. It’s utterly compelling though.
