Ok, I figured out %Content and it's sensitivity. From what I gather, if I set it to 0, I'll get a comparison...if I raise the sensitivity to over the %content, it will disappear since it is no longer close anymore. Using that, I guess I can tell how close a song is to its maximum sensitivity. More or less.
So using that if I have a song that's 50.2% similar to another song at 0% senitivity, then it will only be ~0.2% at 50%...so that means it's near 0 to comparing it to about even 50% closeness, right
Also having reread your post in someone else thread who asked a similar question...experimental is supposed to be more correct in closeness. Did I get it all right?
