Excellent remix
I have to say, I really loved this.
I'm really happy to find a remix that isn't just "Classic Sonic with electric guitars" and even among itself it's amazing.
It sounds more like an original song with cues taken from the original, which I have no problem with. I loved the original Flying Battery, and this really strikes me as amazing.
In fact, it sounds like it could show up in a Modern Sonic game, maybe if Flying Battery had shown up in Generations, with a few minor tweaks.
Also, the title is badass.
