Yeah, I've been meaning to do this song for quite some time, and now was an excellent time.
There did not exist a backing track for this anywhere I know of, so I attempted to create something close using Guitar Pro 6 (nylon guitar), Noteworthy Composer (warm pad, and music box), and a dreamscape-like sound effect. The mixing was a bear, deciding which to emphasize where, to give it an inconsistent but flowing and changing feel.
