I love this, if only because it has such great nostalgic value. I didn't own a Nintendo 64. Of course, we all knew someone who did! You got the song down just perfectly. It's so nice to hear something so positive. You just sound like you're having so much fun with this!
It's great that you show such strong emotion. I can just see Mario as drawn by you. You have been most known for your Super Mario RPG remix. Well, that and the "Brawl Taunts" series. Whatever it is, I had a lot of fun with it.
