This method of comparison useless in music duplicates finding, because, usually, duplicates have different sample rate, different bit rate or information tags, ie. different characteristics (which incompatible with byte to byte comparison).Sound content comparison(which uses Similarity) is different, first sound decoded to raw sound waves and after used in different mathematical calculations to get unique sound estimation (hash). What estimation used in comparison with other sound estimations. This method of comparison give much better results than simple byte to byte comparison or tag comparison.
