MP3 Tag Tools is an application for Windows and Mac OS X that helps users organize and manage their music collections. It is a powerful tool for editing and managing music files and metadata, such as ID3 tags, album art, and other metadata. With MP3 Tag Tools, users can quickly and easily add, delete, or modify any of the ID3 tags associated with a music file, including the artist name, title, genre, album, year, and track number. It also allows users to batch edit multiple files at once, rename or move files, and generate highly-customizable HTML and CSV reports for their music collections. Additionally, MP3 Tag Tools includes a set of built-in tools for fixing common problems with ID3 tags, such as missing or incorrect album art, as well as being able to search and download album art from the internet.
