No, we're not there yet, though I can see why you would think so. Here is the Rare Exports video again - it has less of the keyboard, and it has a vocal component and a darker tone. The one you found could be related - often times composers have a sameness in sound between some types of music. You've come closer than anyone else. I should search again. Very high piano or keyboard, but a drum section, woodwinds, or good synthesizer of all of this.

It's in Wikipedia. It talks about a film that spun off from the earlier short, and "Will be released on DVD and Blu Ray Disc on October 25, 2011." But I haven't seen it, I don't know if it uses any of the same music.
