My only complaint really, is that whatever you're playing on sounds really out of tune. It might just be the key. I encourage you to keep it up though, it sounds great.
the original "Mad world" is one of my favorite songs. you seem to have twisted it int something magical but not as good as the original still I have to give you props it is very unique.
P.S. and now for something completely different
Please contact me if you would like to use this in a project. We can discuss the details.
