ok, here's a weird one:

mp3tag will store ratings as 0-100 I believe (the raw data, translates to 5 stars) in m4a as a  
%rate% atom, which is what twonky and MM and winamp use and np so far.

however windows explorer in win7 will allow you to rate a m4a as well! this rating is NOT in  
the %rate% atom!

so what atom is windows storing the rating to? how do u get mp3tag to read it?

I would guess WMP does the same thing, but I haven't tested it to see.

I saw nothing about any of this here:

[https://docs.mp3tag.de/mapping](https://docs.mp3tag.de/mapping)

or in a search of the forums.

~~I would like mp3tag to read the win ratings, but continue to write to %rate% and prefer it when  
reading if both are present.~~

actually, i would like two separate columns in mp3tag that allowed R/W, one for %rate% and one for the windows explorer atom.

thanks.
