• Opens when "Download Metadata" is clicked for a selected song.
• Displays probable metadata matches based on song title, artist name, and album name.

Fetching metadata

• Retrieve probable matches including artwork, year, track number, and other relevant metadata.

User interaction

• Allow selection of the best matching metadata.
• Option to rename the audio file using the selected metadata.
• Provide undo/redo functionality to revert or reapply changes.
• Stage updates for user confirmation before applying.
