Get your minds out of the gutter...
I just happened to notice something. I have been using a Top Tunes version of "The Dance". It so happens that the title screen does a sort of weird jiggle before it goes to lyrics. I had always attributed this to the way the disc was made. Just so happens I had a singer request the DK version. Lo and behold....same jiggle.
I have a few versions, and tried them. It happened on one other brand ( slips my mind at the moment) as well. The tracks are suspiciously close, but not identical. In part this may be attributed to differing production values, but there were other display and musical differences as well.
Because of these differences I sort of kinda rule out file sharing / thievery but not sure...
Just weird.
