I wrote a song using only one chord!

Harmony is not the only factor to valuate a piece of music. that being said, I decided to create a piece of music using only one chord. somehow removing the complexity of harmony. then I tried to use other aspects of music (rhythm, instrumentation, melody, ...) to keep it away from dullness.
I named this song i7 (one - seven) after the chord.
You can listen to this song on my soundcloud page here:

and this is the podcast I talk about in this video (In Farsi):
