I also don't usually post on this stuff, believing in Thumper's words, but this is really really good. I've found myself listening to this twice, which is a lot for a random internet song, if you will. This actually sounds different from most stuff now-in-days, and the voice is certainly a part. The key changes work great with the song, and it all ends up flowing quite nicely. Very catchy indeed. Good luck with continuing the project (if those are your plans).
