I had this idea and thought it might be interesting... post exactly 2 CDs you own that you think represent polar extremes in music. Like if someone looked at those 2 CDs they'd wonder how the hell the same person owns both...

I'll start:

Necro - Brutality Pt. 1
Zamfir - Greatest Hits


WTF?? I like each in its own way (though admittedly, I can only stomach so much Necro)...
