Justin loaded up a level on YouTube, stuck an earphone up to the mic, and the D3 rep started the Sound Load, but to no avail. "Transfer failed," "Too quiet," "Too loud." That doesn't mean it's a finicky feature, necessarily, just that it's not the ideal feature for the loudest place ever. Owners of the Japanese version haven't really reported problems. I have full faith that it works great in regular noise situations.
I asked the D3 rep if there would be downloadable stages on the US website, and he told me that they were planning a YouTube channel. Furthermore, I was told that Japanese stages would work in the U.S. build.
