iTunes shows nice cover arts for all my mp3 songs. Unfortunately most of them are stored in the iTunes data base and not as mp3 id tags. This makes them useless, if I use the mp3 files with other software and devices.
Is there a way to force iTunes to store the cover arts as mp3 id3 tags?
Or is there a software than can automatically search for the missing cover arts and store them in the id3 tags of the mp3 files?
