Ranking stars stored out of the songs

Hi,

I wonder if the stars based song ranking could be stored in the proper id3 tag instead of the external centralized file.

The problem arises when you move in disk the songs, you loose all the stars because moved songs are recognized as new ones.

The fact is that I can edit the tag in Kid3 but unfortunately is not recognized by Rhythmbox that uses its own ranking system

Thanks in advance
