One Tagger - Free music library management / music tagger

A quick recommendation I’ve been using this for the last year and once you understand the process, it is such an awesome music tagging app for individual song and it is free of charge!

While it might have a few clunky bugs here and there but it is one of the best I’ve tried.

I also use MusicMaster (Mac) for batch tagging conjunction with Onetagger.
