I'm posting a Finnish heavy metal video every day in June in support of the Helsinki in 2017 Worldcon bid. Longer explanation here
Particularly alert listeners might notice that today's song is sung in Swedish rather than Finnish. Finland actually has a substantial number of Swedish speakers, and Finntroll's original singer was one of them.
I have no idea what this song's lyrics are about, but the message I take from the video is "don't trust a bunch of guys wearing pointy ears to detail your car."
