Detailed Description

A header file for the TagLibParser class and Metadata structure, used to parse metadata from audio files.

This file defines a Metadata structure for storing song information such as title, artist, album, and more. It also defines the TagLibParser class for reading and extracting metadata from audio files using the TagLib library. In addition, the file provides utility functions for printing metadata, handling error messages, and extracting thumbnails from audio files.

Note: In the Emscripten build, dummy functions are used because TagLib must be compiled using Emscripten to function correctly in a web environment.
