This little app does one thing and it does it very well. I've tested it and it gets about a 90% accuracy rate (at least for the music I listen to, pretty mainstream stuff). I also really appreciate that it isn't a Widget. I can't stand Dashboard -- what's the point? Very well done and the price can't be beat. It would be nice to get artwork and save the tags to local files (if you use Soundflower you can use that as your audio input and output and test it on your local music files) but even as is it's great.
