Unique.
I've never really heard anything like this, it sounds very unique. While the silence at the end is obviously unnecessary, and this does have a few other defects, it's still a really cool song, and I'm impressed. As I said, it sounds really unique; so unique that I don't think I'll do my usual review structure of Melodies/Sounds - Transitions/Structure - Percussion - Conclusion, and instead split the review into two sections; what's good about the song and what's bad about it.
-PROS-
This song sounds very original and unique. I've never heard anything similar to it, and the different sounds that you used were very weird yet strangely sound awesome. The sound at the beginning was really rough but interesting to listen to.
The vocals were also sung very well. I don't know about the lyrics since the fact that I'm deaf from one ear makes me incapable of hearing stuff properly, and I can't understand the vocals, but from what I heard, they were song extremely well.
The track that's accompanying the vocals sounds cool, and even though at times it gets pretty rough, it still fits very well with the vocals.
There's a cool synth playing some higher notes with cool melodies.
The intro was interesting, to say the very least, and started the song up well. The ending was good too.
The melody on the vocals was absolutely awesome. Not only that, but there were some very cool effects on the vocals here and there in the song which I very much enjoyed :D.
The emotion of anger is clearly present in the song. The sounds you used definitely evoke a theme of anger and revenge, and the vocals were sung with emotion. The atmosphere is also good.
-CONS-
The silence at the end is obviously unnecessary. It's very annoying and if someone downloads this song and puts it in a playlist, when the song ends, s/he has to wait a whole minute for the next song to start or manually switch to the next song, which is a bit inconvenient. It isn't that hard to remove silence, you know :P.

The song is quite quiet. I think amplifying this at least 4 decibels would be better.
The song's level always remains the same. If you take a glance at the waveform of this song, it stays roughly the same amplitude, indicating that there are no climaxes, breakdowns, etc... I definitely thing that adding a bit more to the structure with interesting new sections will not only increase the diversity of the track and make it less repetitive, but even give you more opportunities to portray more effective emotions and more interesting changes.
The percussion was very simple. Basically only a bass drum every 2 beats. I'm thinking that this song could really do with some epic drums from a drum kit playing really slow beats with a good amount of reverb on them. It would definitely evoke more anger to the listener.
The vocals, as Fro pointed out, were weak. Like I said, they were hard to understand, at least for me. The supposedly background sounds covered it up, making the vocals more in the background than the other sounds.
I said somewhere above that the ending was good, although it still isn't perfect, in my opinion. The final note with the vocals was very cool, but from then on I think that you should have faded everything out slowly and gradually, instead of kept it going at the same level and ending suddenly...
Perhaps you could've added a few more bass tones, IMO.
-OVERALL-
This is a very good track, and I enjoyed it. Maybe I gave you a bit of a lower score than the other reviewers, and as you can see there are more disadvantages than there are advantages, but heck, that doesn't mean that this is a bad song. All in all, I enjoyed it, and it has HEAPS of potential, but I think there are still a few more things to fix before I can enjoy this to its fullest, personally. However, keep up the awesome work, and if you ever build on this or make it better, then send me a PM, I'd love to hear a newer version.
7/10
5/5 - because this song is badly 0-bombed and definitely deserves a higher score than it has now.
