About the MP3 Tag Viewer
MP3 files carry their metadata in ID3 tags. ID3v2 sits at the start of the file and holds named frames: TIT2 (title), TPE1 (artist), TALB (album), TRCK (track), TCON (genre), COMM (comments), USLT (lyrics), TXXX (custom fields) and APIC (cover art). Its versions differ in detail. v2.3 is the most widely supported, v2.4 adds UTF-8 text, and v2.2 uses three-letter frame names. The older ID3v1 tag is a fixed 128-byte block at the end of the file with 30-character fields and a genre number.
The viewer reads all of them, decodes every text encoding (Latin-1, UTF-16 and UTF-8), converts numeric genres to names, and shows the cover pictures with their type (front cover, back cover and so on). It then finds the first MPEG audio frame to report the format (MPEG-1 Layer III), bitrate, sample rate and channel mode. For variable-bitrate files it reads the Xing/Info or VBRI header, which stores the true frame count, so the duration and average bitrate are exact rather than guessed.
That makes it handy for checking a music library before importing, finding out whether a "320 kbps" file really is one, pulling out cover art (right-click the image to save it), or seeing what encoder made a file. Tags are shown, not edited. Use a desktop tag editor such as Mp3tag or MusicBrainz Picard to change them.
