I currently don't know what field the application you're using actually uses. It should not get deleted, so there might be some issue with the underlying library not supporting the frame at all, resulting in the frame not getting preserved.

Deletion and writing are technically different things, so Nightingale being "able" to delete the frame does not yield a technical way to write it in a standard-compliant way.

For the cc-licensed or public domain song with a rating from the application you're using, feel free to use any hosting service (Dropbox, Mediafire) or if it is small attach it here in the forums (must be zipped, maximum size 1 MB). There is no mailing list all developers recive, thus I'd be the only one reciving the file if you sent me an eMail. However, if you for some reason don't get it to work, you can contact me at my username @getnightingale.com.

Hi rsjtdrjgfuzkfg, attached please find a file that has a rating with 4 stars from another program. In the windows browser you can see this rating if you add the rating column to the browser. As soon as I change the rating in nightingale the rating in the metadata disappears. Best regards, Lupo

Technically, that file uses a POPM frame tied to the eMail "MusicBee", a play count of zero and a rating of 196/255.

Triggering a retag does not remove the POPM frame for me. Writing a rating sets the NIGHTINGALE-RATING frame properly, without affecting POPM. So far, everything works as expected.

Now the crazy part: the windows explorer displays the rating for "MusicBee" while the file is unaltered, while it displays no rating after a retag. Technically, the frames are unaltered, however, the frame order changed. That shouldn't cause the issue, though.

What's probably more important is that the new ID3 tag is of version 2.4 instead of 2.3. Windows Explorer does not properly handle ID3v2.4 tags according to multiple sources, even in Windows 8. Seems like Microsoft does not care for the "new" standard (which actually is quite old)... and that means that we cannot do anything about it.

Thank you rsjtdrjgfuzkfg, roughly I understand. It's really strange and a pity that they cannot agree about a common standard! Please keep me informed if there is anything new in this matter. And one more question: is there an easy way to handle the ID3 tags with a program? E.g. take the ratings from XML file and put them into this 'email-field' or opposite?

Creating POPM tags from the nightingale-specific tags should be possible with tools like mp3tag. In that example, use a Tag-Tag rule for POPULARIMETER with

Code:

your@email|$if($eql($meta(NIGHTINGALE-RATING,0),1),1,$if($eql($meta(NIGHTINGALE-RATING,0),2),64,$if($eql($meta(NIGHTINGALE-RATING,0),3),128,$if($eql($meta(NIGHTINGALE-RATING,0),4),196,$if($eql($meta(NIGHTINGALE-RATING,0),5),255,0)))))

and replace your@email with your actual eMail address or some generic name. However I'm not fully sure if that works properly as I don't have any tool reading that field according to the standard.

Some time ago, fcastillo wrote that he has written some scripts doing what you want:

However he did not publish them. He was interested in implementing POPM properly, but I haven't heared from him in a while.

Thank you very much. I will try it when I find some time.
