Happy birthday Sonic 1 indeed.
This was a pretty cool remix done of the Scrap Brain Zone theme which is my all time favorite theme in any Sonic Game (i would cheat just to get to that level with a quickness i liked it that much lol) anyways this was a little less hard & jammin than what i'm accustomed to hearing but i did like this techno/trance like style and thought it fit quite well too so nice but creative there,overall you did a great job on this remix. =D
Please contact me if you would like to use this in a project. We can discuss the details.
