I really like it, but there are some things you could improve on. The lead "Dubstep" synth I found very repetitive and it made the entire song sound like it was repeating it self sometimes. I love how you managed to keep the feeling of the original ToE series which I found you didn't do very well on with ToE III. This one was a huge improvement, and I like where you are going with your style, which leads me to my next point.
When the song kind of drops out and fade back in, it sounds like the song is ending and replaying. This goes back to how repetitive the main synth is, but that's aside the point. I would have liked a smoother transition between those parts, rather than the audio just completely cutting out and fading back in.
Other than that, I really like it, and I have downloaded it for personal listening. Good luck with future releases!
Reviews for "Theory of Everything IV {Fan Made}"
Very good :)
If the sound design were better, this would be better than djN's ToE 3 because it's a ton more original.
Its fine :)
It is nice :D
