Add identifying info to music files

Is there a way to automatically add titles and identifying tags to my music files?

MusicBrainz Tagger, a service of the non-profit MusicBrainz organization, helps you identify and clean up the often poorly labeled metadata tags in your digital music closet, such as artist, song and album name, and so on. Download the free program to your Windows PC and it goes to work, cross-referencing the acoustic fingerprint of each untitled track with its online database and then filling in the missing information for you. The program has a better than 80 percent success rate.
