My comments are going to be almost exactly the same as the last song I reviewed. I really like the melody that comes in at 1:09-33, it's definitely the highlight of the song. Compositionally it's a big mess and you should get rid of all the extraneous melodies (like the part up to 1:09). It's not bad, but it is not as good, and why have less than great stuff in a song that has great stuff?
I also really like the crazy arps towards the end!
BTW i would just like to point out that I'm start enough to know that the title refers to a square wave. yep. smart. i'm smart. that's me.
