Wow.
This song is absolutely superb. Contrary to the reviewer below who gave a 7, the random FX fits perfectly with the song, and it shouldn't disrupt the song because it lands on a beat, as do all the other FX, and therefore they only serve to reinforce the song. All the FX is perfectly timed to the song, giving it an amazing feel. Beautiful melody, beautiful execution, probably room for improvement, but thats trivial - there's always room for improvement.
