Thanks for the info, paultaylor. I didn't want to drop $30 on it if Jaikoz was going to be missing a backend a year from now, but I'm otherwise quite happy to go out and buy it now. I used to use picard, etc and am pleased to see there is still a great OSX utility for this.

In response to scf Musicbrainz is not going comercial, but it has always provided the data to commercial companies for a price (e.g last.fm, bbc). Jaikoz has a very close relationship with the people behind Musicbrainz and10% of every sale go to Musicbrainzinz so dont worry there is no impact on Jaikoz

Does this still use the musicbrainz database? I heard that is going commercial. How will that switch impact users of Jaikoz? Or will it?

Yes, it may not be the best aqua interface around, but it's definitely the best tagger and media manager around. The developer, Paul, is very helpful and is not asking much with those 15 pounds. Recommended app.

While the GUI is admittedly not at all Mac'ish (primarily because it is Java and cross-platform), the application is the absolutely best and most efficient tagger I have used. You can configure it, point it at your music library, and watch as it uses the acoustic fingerprinting and database lookups to automatically fix your tags, get artwork, and organise your collection. Author is constantly improving it too, and directly takes feedback from users.
