Regex Tester & Validator

Matches music file names in the 'Artist - Title.ext' format, capturing the artist name, song title, and audio format (mp3 or m4a) into named groups. With multiline mode, ^ and $ anchor each match to a single line, making it ideal for processing an entire directory listing at once. The character class permits letters, digits, apostrophes, periods, spaces, and parentheses in names. Useful for parsing music libraries, extracting metadata from filenames, or batch-renaming songs.
