Brief but good
I guess the lack of a title allows the listener to come up with his or her own interpretation. I think this was probably intended to be a scary song. It would have made more sense that way if it had been released around Halloween. It kind of has a punk theme to go with it. It even has a little bit of a tone of craziness given how bizarre it can be at times. It's amazing how many styles you are able to create in only a minute and a half.
It has so much variety for a short song, which I think is great. I like how you are trying to appeal to different kinds of tastes with it. A good song is something where it doesn't matter how long it is. In fact, there's so much going on, I even have trouble figuring out that it's even starting over. The voices are pretty nice too.
