Release date not populating into Rekordbox 5.4

Any updates? This field would be a huge help.

I have WAV files and MP3's as well that do not populate.

Sorry, no updates -- and WAVs also don't store the Release Date metadata, so that wouldn't import. Are you sure the MP3s had the data in the proper tag prior to import?

Yes, all MP3, WAV, AIF, FLAC, etc. have the correct tag in the YYYY-MM-DD format however out of 5000+ songs the release date does not populate into Rekordbox. All other categories seem to import properly.

WAV also stores it in the TDRL field within the footer, but it's non-standardized, so not imported.

FLAC and M4A stores it in the RELEASETIME tag, but it's not imported.

AIFF and MP3 are the only two filetypes that, when imported to rekordbox, will have the Release Date values read. MP3s store this in the TDRL ID3 header frame (known as "release time"), AIFFs use the same ID3 frame, but it's in the file footer. They must be in YYYY-MM-DD, as you note.

If they're not importing, please verify the data with a 3rd party app, such as iTunes or a tag editor, because they should certainly import.

Thank you for the insight. With that said, is there any other tags besides comments that import to Rekordbox directly? For instance I could write the release date to comments and it would import. Would I be able to do this with any other ID3 tag?
