I have recently discovered that some of my Albums have inconsistent Album Gain values. I use foobar2000 converter for these and it happens when an album contains more than one composer or date. I did not notice that foobar2000 sorts those together for ReplayGain calculations.
Is there a way I can filter my albums to find only those that have this condition? It can't be done by folder because some folders purposely have multiple albums in them. (Don't ask; it's a "classical" thing.) It has to be done by tags:
List all %ALBUM% for which %REPLAYGAIN_ALBUM_GAIN% is not a constant value.
Can anyone help me with this? Thanks.
