Good Dimmu songs to start with: Mourning Palace, Kings of the Carnival Creation ... and just about everything else from the albums Enthrone Darkness Triumphant & Puritanical Euphoric Misanthropia.

Filth is becoming quite commercial as well. I don't really know why though, I don't think they are -that- easy to listen to, yet fucking 14-year olds with their 50 Cent shirts have started to like them. It's strange. I guess it's because of Dani (who is a short fucking moron, by the way)
