Dude, you got skills.
A 10 because of its outstanding originality and randomness, its superb recording and melody. Your voice is perfect for this type of song, and I am very impressed by the whole song, overall.
Just a little thing you got to fix, though. There is about 30 seconds of complete silence at the end. Trim it off; it's unnecessary.
Other than that, I think I've said enough. Great melody, theme, voice, and everything was in sync. I don't think I heard a single thing wrong.
Excellent! I just voted you 5. Didn't make much of a difference, though, since you're currently at a 4.85
