Potential Tag Rating Issue

[nypd]

Hello,

I'm running into a strange and really specific star rating issue.

Some background Info:

What I'm trying real hard to accomplish is to be able to sync star ratings between my phone using the GoneMad Music Player and my Musicbee client on my desktop. I am using the application syncthing to sync music files back and forth. So what I would like to do is be able to listen and rate music at work, and when I get home, have my phone automatically update the mp3's in my music library. And vice versa. That part I have working great, any changes I make in MusicBee gets reflected on my phone, and any change I make on my phone get reflect on MusicBee.

The Potential Issue

It seems MusicBee and GoneMad do not agree on how 2 and 4 star ratings should be written. So for example, If I rate a song in GoneMad with 2 stars it gets synced to my desktop, but MusicBee then reads the rating as 1.5 stars. Same thing happens with 4 stars which then MusicBee reads as 4.5 stars.

Now it seems like MusicBee writes that star rating to the "popularimeter" tag.

A 2 star rating in MusicBee gets written as: "MusicBee|64|0"
A 2 star rating in GoneMad gets written as: "GMAE|86|0"

A 4 star rating in MusicBee gets written as: "MusicBee|196|0"
A 4 star rating in GoneMad gets written as: "GMAE|223|0"

Here are Mp3Tag screenshots of the exact same file, but different music application writing the  tags:

MusicBee



GoneMad


Now the strange thing is the GoneMad player reads both the MusicBee ratings and its own ratings perfectly. 1/2/3/4/5 star ratings show up as expected. However I can only get 1/3/5 star rating songs to show up in MusicBee correctly.


Conclusion / Question:

I guess my question is if MusicBee is handling this "popularimeter" tag correctly? I have been doing lots of test and trying our various versions of MusicBee: 2.4, 2.5, 3.0 but they all behave the same way.

I also have been talking to the GoneMad developer in this thread: http://gonemadmusicplayer.proboards.com/thread/801/beta-saving-ratings-potential-issue?page=1. In that thread you can see a lot more examples and images of me trying to figure this out.

I'm willing to test stuff, just let me know.


Thanks

There is no ID3 standard for the values used for a rating. MusicBee uses the same scale as used by Windows Media Player/ Windows Explorer/ and MediaMonkey. Its not something i would change.
You would have to ask the GoneMad developer the reasoning for the scale used by that application.

Ah alright. A shame the scale does not simply go from 1-5 lol.

Thanks for the responses, I'll post here If I get any further.

There is no ID3 standard for the values used for a rating.

Technically there is for one part, but everyone ignores it.
Ratings start at 1 not 0
Rating = 0 means rating is unknown
0 rating is not equal to being banned

As a quick update, GMMP has been updates to beta 5: http://gonemadmusicplayer.blogspot.com/2016/09/beta-5.html

Adjusted saved value for id3 rating tag to match what MusicBee writes

This has resolved my issue!

This has resolved my issue!

Thanks for raising this issue with the GMMP devs.  Even though I'm a PowerAMP user myself (wavering though since it doesn't support the rating scheme discussed above), I'm sure there are others here who use GMMP that appreciate your report.

I just saw that update. Thanks!
