I don't know where it came from, but it was in a folder with one other song by the same artist. I managed to find out through my awesome google-fu and my horrible transliteration that it is from the band Nightmare. I didn't even know I had any of their stuff, so I kind of have to wonder how long this has been floating around various HDs. so weird. Also. I hate Christmas music. Like. A lot.
I also feel I should mention that I found another weird Jrock MP3 just labelled "Jigoku" that is thrashy, screamy, has music box samples of Jingle Bells, and ripped samples from WHAM's holiday song "Last Christmas" WHAT IS THIS STRANGE THING?
