So here I am:
Hammerite: I liked the Idea to work with channels. I especially liked, the break at the end. You stayed very long at one height, then you bring it suddenly on a very low level. I think that is impressive.
Djres: These blurp impression I got was followed by a kind of rush. It was a very interesting experience as well. It was very symmetrical an equilibrated. Interesting...
Jelfish: You mainly work with one sound, that seemed to be completely synthetic and slightly changed it. You made many variations but all were different although they were somehow similar. It reminded me a bit of Morton Feldmans approach to music.
ghormak: I liked this more mathematical approach. I tried to listen very long to it, to get the slight changes. I think this is something that can be sent in space very long, and shows that we are somehow intelligent...
knum: A very minimalist try, that consists of multiple ostinati. Very clear from its basic puristic idea.
maaark: A very entertaining one. Somethong for late night I'd say. Do aliens have a guitar?

Thaatiba:
I think especially the beginning is very strong. Later you worked more with repetitions. I also liked the very aprubt ending line.
So, after all we sent the whole bunch of music into space. It took more than 2 million years until they sent us an answer. An answer, that couldn't be misunderstood...
The winner is:
