@Ices, Picard only writes the tagfields. Kodi uses the filenames to sort the files. You could use a rename tool that is able to execute batch commands. I use Advanced File Renamer.

I never said it was easy Organizing your music (and video) files for Kodi, is a time consuming process.

Actually Picard can rename the files now. Better still, it can rename to include the disc number (if multi-disk album), it can create a folder for each artist and create album folders under each artist folder. Its renaming style makes it very easy for scrapping by Kodi. It is still time consuming making sure the correct album is identified and tracks are properly matched but it saves you a lot of time. Update Picard to the latest version, Go to options and tick both options for "Rename Files" and "Move Files".
