Tagify

If you have a large collection of audio files on your computer, you probably tend to it and are careful about each file's metadata. However, modifying metadata can be difficult without the appropriate tools.
In the situation mentioned above, you can turn to third-party applications such as Tagify that can help you achieve quick, convenient results.

Modify metadata

You can turn to this application if you need to edit metadata for multiple MP3 files on your computer without significant efforts. In order to do so, you just need to load the desired items by using the "Add Files" options and browse the corresponding categories.
You can replace all the tags that match certain criteria, remove extra spaces from all the tags, format metadata text, remove Serato tags, export tags to a filename and import them from a filename.

Various criteria

Tagify enables you to edit multiple tags in one sitting by loading several files and choosing the columns you want to be edited. You can replace tags by using a find-and-replace system.
Among the supported columns that can be edited, you can find "Title," "Artist," "Album," "Comment," "Genre," "BPM," "Composer," "Grouping," "Label" and "Remixer." It is possible to select all or only a few of them by ticking their checkboxes.

Format text

Aside from replacing tag information or removing extra spaces, you can also format text fragments by capitalizing them and converting them to upper or lower case.
The columns are the same as stated above. Additionally, you can edit each item individually by typing comments, editing the years and modifying other metadata strings such as the title, artist, filename, track number, genre or composer name. It is also possible to choose a cover art image from your PC for each MP3 file.

Handy tag manager that supports bulk operations
