Aha. You're interpreting the test results incorrectly. (You must be
thinking that a high percentage is good...in fact a high percentage
means something very different here) The log you posted indicates that
you can't distinguish between the lossy and lossess tracks.  You would
want to see a % (p-value) of, say, 5% or less. But I'd be impressed with
even 10% or less. bottom line, the results you posted indicate that you
can't distinguish between the lossy and lossless file.    More info on
interpreting the ABX test here:
