I have the ISRC check marked in the options menu and subsequent to ripping the CD discs I do not find any reference to ISRC in the metadata provided. I am looking at the metadata by right mouse clicking on an audio track which brings up and select options, properties, and then can select from "Security", "Details", "Previous Versions", "General", "Audio Properties", "ID Tag", Digital Signatures". Shouldn't there be a field for the ISRC 12 digit value to be displayed which may then be decoded?
