Wow. Awesome. I thought it was a little whack until around 1:20 when the chord progression becomes prevalent. Awesome job, dude. This is really great for playing in the background while working or writing or pretty much anything. Honestly, I have no clue how you did this, but even though I can't detect any specific changes throughout most of the song, it never seems repetitive in the least.
Whatever score this song gets, it deserves better. :D
