It's a fair criticism that this application does not have a user interface that lives up to what you expect from an OS X app, but that is the limits of a fair criticism for Jaikoz - and mostly due to its use of the Java user interface libraries to keep it multiplatform.

First, there is almost no other tagging application on either Windows or Mac (and this one also works on Linux) that has the feature set of Jaikoz. The UI sometimes gets in the way of understanding the power of it, but Jaikoz definitely has power.

Second, you have nothing to lose by trying it for a bit with the trial download. For anyone with a large music library that wants to clean it up with a) proper tags, b) proper artwork, and c) using acoustic fingerprinting to track the metadata then Jaikoz is for you.

It uses MusicIP acoustic fingerprints to automatically identify an audio track and then the Musicbrainz public "social networking" database to match the acoustic fingerprint with the metadata.

Speed is also not an issue, so don't let the "Java" mislead you. It's very fast at performing the acoustic fingerprinting and retrieving the metadata. Just try it.
