Despite its everything-but-the-kitchen-sink interface, Ultra Tag Editor makes a fine tool for editing ID3 tags. The quick installation process automatically detects your default system language and makes the appropriate changes in the interface. The application window overflows with buttons and tabs, but most users will get their bearings after spending a few minutes with the included help file. When you manually select a file folder or insert a CD with MP3s, the program swiftly scans the contents and displays the relevant files. ID3v1.0 and v2.0 tag information appears in a neatly organized side-by-side display. A useful summary bar below provides information such as track size, duration, bit rate, encoder, and copyright. Other features include a music player, a batch-file renamer, and a batch-tag converter. Ultra Tag Editor isn't the most elegant utility we've seen, but otherwise it's a perfect companion for people with huge MP3 collections.
