Three old ones:

The first is a dedication to one of my ex-neighbours who introduced me to the music program I'm most of the time using.

Heartbreak is supposed to represent my view on a couple's tensions which happened to be two of my old friends.
It has lyrics made but I'm not sure how well they fit with the music. Plus, I'd need some proper voices for it

The third was started on guitar with an old friend of mine. It has a "religious" background the idea being a war between angels and demons as seen from human's view.
I don't know where the lyrics are. I remember writing them somewhere but I have no idea if I still have them anywhere...

I think the second and the third were started somewhere in 2007 if not earlier. The first, possibly 2008-2009.
