While I question some of the sources they are based off of, this is still a very interesting site which gives a "score" on an albums dynamic range. I'm not sure what they use as algorithm, but something like plain recorded speech would score the highest. Looking through both extremes of the list is very intriguing. List of LEAST dynamic albums (meaning as loud as humanly possible, Hat's off to you Iggy Pop and Venetian Snares, I knew you could do it!) http://www.dr.loudness-war.info/index.php?sort=dr&order=asc List of MOST dynamic albums (It might not shock you to see some very dynamic artists up here, but remember only the most dynamic recordings score this high, usually Japanese versions etc.) http://www.dr.loudness-war.info/index.php?sort=dr&order=desc Personally I find the least dynamic list very compelling and the albums have a very distinct quality to them.
