As haunting as the lyrics are (and the more I actually listen to them, the more haunting I find them), it's not the lyrics that get stuck in my head, and I kept finding the song looping through my mental background before I even knew what the lyrics said. It's just those simple few piano notes with the mildly discordant, "noisy" electronic background loop. So evocative.
Ah, well - a few more rounds of Oddworld: Stranger's Wrath on the faithful X-Box cures all. Except maybe leprosy. (But I don't have that, so it's still a universal palliative as far as I'm concerned.)
