This just goes on and on and on...can't be bothered to write a good review atm, so sorry for that i guess :S
Thirty seconds of original work stretched into a 3.5-minute song. It was actually kind of good, if you don't mind hearing the same thing over and over. The ending doesn't work. Immediate drop-offs are awesome if done right, but this piece doesn't merit one.
Please contact me if you would like to use this in a project. We can discuss the details.
