My MP3 collection is a mess. I have a bunch that are missing information on song name and which albums they belong to. Thanks to Joi Ito for the link to the following new service. I will see if this service helps clean that up.
A blurb directly from their site.
“MusicBrainz is a community music metadatabase that attempts to create a comprehensive music information site. You can use the MusicBrainz data either by browsing this web site, or you can access the data from a client program – for example, a CD player program can use MusicBrainz to identify CDs and provide information about the CD, about the artist or about related information. You can also use the MusicBrainz Tagger to automatically identify and clean up the metadata tags in your MP3 collections.” [www.musicbrainz.org]
