Are you sure about that? Because I have many albums in my memory card and none has album art in the ID3 tags. But when I put me card in N900, most of the albums had the correct album art.

I thaught that the album art was identified by N900 bacause I had previously changed the album art in 5800 music player.

If you are correct and N900 only identifies only embedded in the ID3 tags, album art, you have in mind any good tool to edit the ID3 tags in my existing library?
