My name's Alex too >_< and I must say this is really good; I don't see why the judges wouldn't allow this, because this is pretty authentic IMO, most arrangements like this are kind of bland and not really engaging. Maybe you have to know the original material to like it, but man this is good. =D
Don't give up if the judges say 'No'; even if they do, this remix is staying on my playlist...can't wait for an update on it.
