Spotify is dangerous... You sit down just to look up one song, and suddenly it's two hours later... And there's some seriously weird stuff on your playlist. *grins*

I don't know how much of a metalhead you are, but if you want odd metal I suggest Finntroll. Slaget vid Blodsälv for starters. Can't get much weirder than death metal combined with Finnish folk music (complete with accordion...). Or maybe that's just me...
