id3_get_genre_list — Obtiene todos los valores posibles para la etiqueta género
id3_get_genre_list() Retorna un array conteniendo todos los posibles géneros que pueden ser almacenados en la etiqueta ID3 correspondiente. Esta lista fue creada por Eric Kemp y más tarde ampliada por WinAmp.
Esta función es útil para proveer a los usuarios una lista de géneros donde puedan seleccionar uno de ellos. Al actualizar la etiqueta ID3 siempre se debe especificar el género como un entero entre 0 y 147.
Retorna un array conteniendo todos los valores posibles para la etiqueta ID3.
