worst album you have ever listened to?

[Till]

Ok. There has been so much music already written and produced. There are uncountable tracks which are just horrible. Like I call them myself "musical environmental pollution"
But sometimes there are several of this shitty audio files together on just one disk...
So, my question: What is the most horrible album you ever listened to?

I don't listen to a full album if I'm not enjoying it at least 3 songs in.

The only answer I really have is Metallica's St. Anger album.
