Ripping old music and trying to export songs into files that Win10/iTunes can easily import. It appears the artist field does not successfully get written for M4AA(AAC) format (other fields appear correct–Track, Album). It shows as blank in the Windows 10 File Explorer and “Unknown Artist” in iTunes. If I export the same set of tracks as MP3, it shows up successfully. Any obvious pilot error sorts of things I should be doing differently, or is this a missing capability for AAC.
