BINAERSTOFF  Great tool so far! Unfortunately it deletes existing artwork and itunes ratings...  
(Version 0.3)

PELICE  Excellent! Very powerfull and fast!

He need only 1 more features: get tags from name!

REMEDIAL  Great app, in my opinion. Only things lacking are the ability to add additional columns for information like bit rate and album artist (not just the plain ole artist field) and the ability to add artwork to files (would be especially great if it could get artwork from amazon.com).

I didn't find that it removed artwork from files during my usage.

I must say that this seems to only mp3 tag editor that I've found that corrects files so that they show up properly (and not in the unknown folder) on my Sansa Clip.

With the additions that I mentioned, one might never need to edit a file in Itunes ever again.

SERHIJ  Program crashed spontaneously as soon as started to look for the tags. :(

DAFABS  Fantastic prog. I had a load of untagged MP3's, got the tags for most of them. Saved me a load of time. Thanks to developer.

MORSMORDRE  It works great so far. The only thing missing for me is the ability to add/edit album artwork.

DAVIDE RIVOLA  Really nice software. One feature I miss is the possibility to change the order of the songs to tag. This is necessary when dealing with an album without track info in the title

MOLOKO_MAN  Very easy to use. Musorg works like a charm. I had several albums with no id3 info and the filenames were 0001.mp3, 0002.mp3, etc. Withing minutes I was able to get all the album info. Great work. Could use a status bar when saving tags, though.
