This is a great tool for managing large collections and their associated metadata. We have over 26,000 songs in our library and this did a great job allowing us to manage the tags.

The only drawback I've had with it is that it seems to embed multiple versions of album artwork with the files. It would also be really helpful to be able to tell the software to *not* fetch artwork under a certain size. (It stinks to have an awesome interface up on a big flat screen, and it's scaling 112x112 images up to fill a 50" screen... and weeding those all out by hand takes forever).

End to end though, this a great software and I highly recommend buying it if you have a large collection to manage.

(One other note, with really large collections, you have to process them in chunks unless you have tons of RAM. We have 4gb on the machine we used for this, and we could still only process around 10,000 songs in one batch... )
