MIDI made in Anvil Studio, then there was a whisper on the wind, and the MP3 appeared via Fruity Loops. Uses Edirol Orchestral VST and a bunch of free soundfonts found on the internet.

Although I picture this as the backdrop for some good mystery solving, I suppose it could apply to a number of scenarios. There's a nice driving factor to this song, so maybe some kind of training or other effortful activity.

If you want a proper loop, then a message you should send.
