Hi Does this not just show the difference between the reference values set between ReplayGain & MP3Gain? MP3Gain can have a user defined value therefore when you are IN that program if you analyse the track and your reference value is set to 93dB - the values in the list below it are referenced to this value. Going into MP3Tag or Foobar - shows you the stored "replaygain" value which is always referenced to 89dB (I think). MP3Gain will let you change the reference point (as said above) but his only works when the value is written to the file (ie the track data is altered - rather than reading a value from a tag). Otherwise the analysis value stored to tag is like the value stored to tag from Foobar's Replaygain... Hope that makes some sense!!
