/// Musics are sounds that are streamed rather than completely
/// loaded in memory. This is especially useful for compressed
/// musics that usually take hundreds of MB when they are
/// uncompressed: by streaming it instead of loading it entirely,
/// you avoid saturating the memory and have almost no loading delay.
/// This implies that the underlying resource (file, stream or
/// memory buffer) must remain valid for the lifetime of the
/// sf::Music object.
///
/// Apart from that, a sf::Music has almost the same features as
/// the sf::SoundBuffer / sf::Sound pair: you can play/pause/stop
/// it, request its parameters (channels, sample rate), change
/// the way it is played (pitch, volume, 3D position, ...), etc.
///
/// As a sound stream, a music is played in its own thread in order
/// not to block the rest of the program. This means that you can
/// leave the music alone after calling play(), it will manage itself
/// very well.
///
/// Usage example:
/// \code
/// // Declare a new music
/// sf::Music music;
///
/// // Open it from an audio file
/// if (!music.openFromFile("music.ogg"))
/// {
/// // error...
/// }
///
/// // Change some parameters
/// music.setPosition(0, 1, 10); // change its 3D position
/// music.setPitch(2); // increase the pitch
/// music.setVolume(50); // reduce the volume
/// music.setLoop(true); // make it loop
///
/// // Play it
/// music.play();
/// \endcode
