TagRunner scans your collection of music files and automatically completes ID3 tags, adds lyrics and album cover art. It retrieves the information from a combination of online resources, and presents you with a report to review the data before writing it to the ID3 tags. You can also fine-tune the data and manually add information that could not be retrieved from the web. The program needs at least some basic artist or song information that it can use as a basis for the web searches - it cannot analyze and recognize the actual audio content of the files. However if your collection includes at least some clues as to the content of the files, you can use TagRunner to complete all your tags with the complete information. TagRunner supports MP3, WMA or OGG files. The trial version can tag up to 25 files and will no longer function once that limit has been reached.
