"Rate Box" itunes atom

Hi guys,

I'm going to assume that this question is probably best suited for Dano or Florian, but if anyone else knows, please do chime in!

Does anyone know anything about the "Rate box" atom as described in this post here:

I would really like to tag my files with this atom, and if MP3Tag allows for it to be done, it would simply be great!

Florian, any insight into this?

(This is my one and only bump). :slight_smile:
