/**
* MusicAPI - Singleton class that provides a unified interface for accessing music streaming services.
*
* Supports multiple providers (primarily Tidal) and includes functionality for searching,
* retrieving metadata, streaming, and managing playlists, artists, albums, tracks, and podcasts.
*
* @class MusicAPI
* @classdesc Manages API interactions with music providers and provides caching mechanisms
* for cover artwork and video metadata.
*
* @example
* // Initialize the MusicAPI
* await MusicAPI.initialize(settings);
*
* // Get the singleton instance
* const api = MusicAPI.instance;
*
* // Search for tracks
* const results = await api.search('query');
*
* // Get a specific track
* const track = await api.getTrack('track-id');
*
* // Get stream URL
* const streamUrl = await api.getStreamUrl('track-id', 'HIGH');
*
* @property {LosslessAPI} tidalAPI - The Tidal API instance
* @property {PodcastsAPI} podcastsAPI - The Podcasts API instance
* @property {Object} _settings - Configuration settings
* @property {Map} videoArtworkCache - Cache for video artwork data
*
* @throws {Error} Throws if instance is accessed before initialization
* @throws {Error} Throws if initialize is called more than once
