There's one thing many of us music loving computer users have in common -- messy music libraries. Over the years of collecting tracks, our libraries get littered with mislabeled or unlabeled tracks, missing album art, and more. Luckily, there's some great software to clean this up and get better organized.
- MusicBrainz Picard
TuneUp is a pay program, but you can test it out for free on up to 50 songs. The program normally costs around $40 for an annual subscription or about $50 as a one-time purchase. TuneUp works on Windows and OS X. It allows you to tag all of your files in a batch if you'd like. The interface is simple - you drag and drop files to TuneUp from either Windows Media Player or iTunes and TuneUp will find the proper artist, album, and other song data including album art.
MediaMonkey is a free piece of software for Windows only. There is a limited batch tagging feature - it only works on a per album basis (you can tag multiple songs as part of the same album). MediaMonkey also is a media manager/player, so if you wanted to rid yourself of iTunes or Media Player, this is a free option. Compared to TuneUp, MediaMonkey does give you the option to choose which album a song came from. So if you really want to use the album art from the original album and not a "Greatest Hits" collection, you'll have that ability.
This free program is cross-platform and works on Linux, Mac OS X and Windows. MusicBrainz Picard does handle batch tagging. Additionally, MusicBrainz Picard has Audio Fingerprinting which allows for very accurate music tagging. That feature is turned off by default. You'll have to go into the Options menu to activate that feature.
