How to set music rating

Hi,

I’ve got loads of music files, and thought a good way of finding my best songs was to create a smart playlist which looks for 5 star rated songs.

I would then browse through and mark my best songs with 5 stars – I did a lot of this in Windows explorer, setting the rating in the mp3 files details.

This worked, but I found several tracks which already have a rating of 5 stars, so I set these tracks to have a rating of no stars in explorer.

But when I look in Kodi, the ones I’ve set to No Stars will have their 5 star rating.

I’ve tried rescanning music, but no joy.

If I set them in Kodi to no stars, it works – but this takes ages and Windows explorer is much faster.

Am I missing something, why does Kodi ignore the rating of the ones I set to No Stars?

Thanks
