TuneTagger for Mac

From Ellipsis Productions:

Browse through anyone's iTunes library and you're bound to find thousands upon thousands of songs. Some of them probably were ripped from CD, some of them came from the iTunes Store, and still others may have been downloaded (legally, of course!) from a variety of other sources. So when you want to find that right song to listen to at the right moment, it's important to have your songs tagged with as much correct information as possible. But with so many songs coming from a variety of different sources, how can you easily manage your iTunes library?

With TuneTagger, of course. When you play music through iTunes, TuneTagger finds all the information about that song on the internet for you, without you having to do a thing. TuneTagger fetches official album information from the CDDB music database so that your songs will have the correct title, artist name, album name, year, and track number. It retrieves high quality album art automatically, and it even fetches lyrics without you having to search through various webpages or lyrics sites. It takes the work out of tagging.
