Never-ending update

It seems that the update command won’t update the database:

(ins)foo:~$ beet update
Radiohead - The Bends - Street Spirit (Fade Out)
  label: EMI -> 東芝EMI 株式会社

(ins)foo:~$ beet update
Radiohead - The Bends - Street Spirit (Fade Out)
  label: EMI -> 東芝EMI 株式会社

(ins)foo:~$ beet update
Radiohead - The Bends - Street Spirit (Fade Out)
  label: EMI -> 東芝EMI 株式会社

What gives?

Hello! This can happen when one track on an album has a different album-level field from the rest of the tracks. Can you check the label field for the other tracks on The Bends?

Thanks, Adrian. Indeed, that track had a different label. I reimported the album and all is OK now. I wonder why this happened. Somebody modified the label for the album on MusicBrainz, but for some reason mbsync failed to update this particular track.
