Wow! Pseudopod rockets ahead of everything else as usual. Three stories. Lovely jubbly!
#1) seemed a lot like a gross-out story, and it did have the intended effect- I felt pretty physically sick listening to it. Not the sort of thing I enjoy though... to be honest until PP I didn't like horror at all, but I've got into the whole pyschological side of things of late which is helping to break down the stereotypes of horror as.. well, screaming people and axe murderers.
2) I liked. The mood was maintained right through, the singing awful, the imagery interesting to say the least. I thought.. this is how the world ends, not with a big fight but with everyone individually giving up. Cheery stuff.
#3) Woah. JUST having listened to this might bias me a bit, but I cannot say how much I loved this story. The format was fresh, the ideas disturbing yet fascinating, and the "characters" described in a deeply human and personal way really struck a chord with me. (more cliches coming up) I agree with what deflective said. If you have these issues, you can't view it as your fault, some failing in you that makes you evil or bad or wrong, some choice you make. It's something you're not in control of. You can't externalise it- it is and always will be part of who you are- but you shouldn't kill yourself just because of that. You need to learn to deal with it.
The horror part of this story really hit me, as it's supposed to, with the last of the three segments, about padeophilia. Like others have mentioned, we do dehumanise these people- but they are people rather than just beings. What makes this true horror, however, is the way that it's inescapable. You're held at gunpoint, your house burgled, you're attacked by zombies... all of these things will end, there will be some relief or release from them. When the issue isn't external, when it's a part of you, inside you, and there's no way out- when it smothers everything, that is true horror and desperation and despair.
...
So, enough of that rambling. On the whole, fantastic stuff and I'd like to see it again. Thanks Al, and thanks of course to the authors.
