This is really good. I forgot when I first favorited it, but it was a long while back, definitely when I was still in high school. The Audio Portal definitely didn't look like it does now. It's songs like these that inspire me to cover music, and to try making my own.
There's just one thing I noticed in this particular remix that's off. Don't get me wrong, it doesn't bring the song down one bit, it's just that minor that it doesn't really need to be bothered with. There's one note in the main melody that's off, the second one from the beginning of said melody. The way you have the melody, it starts at C-sharp, then goes up an octave on the third note to the next C-sharp (which is how the melody is, it goes up an octave on the third note). That being said, the second note should also be C-sharp, but you have it at F-sharp. Again, it's really minor, and you don't need to bother with it, but I thought you'd like to know.
Now, obviously, you've been active since this song, because you have songs going out to 2009, but you need to come back, man! Make some more for '13! Don't stop, man, because you've got talent and it rocks (song lyric pun intended)
