Some of my files do not have complete ID3 tags and some have typos or small differences in writing – so finally, my portable player sees “Mr. President” as different artist from “Mr President” and so on.

I would need some tool which could search similar tags and then allow me to correct the typos or for example override artist in all selected files by manually entered text.

The same with empty tag items – sometimes, the track name, album etc. is OK, but the artist is missing etc.

I'd like to do this without touching the audio quality, of course (but this should be no problem, I think).

I already tried tools like:

• Winamp
• Songbird
• other players
• Tagscanner – the most advanced free tool I tried. However, it is not able to to solve the problem with similar tags.

Do you know such tool? Preferably free and for Windows, if possible. However, if you know some commercial app able to do this, please let me know.
