Hi mdorantes,
in regards to your list, I found the following 4 style names in the PA3X. I haven't had a chance to download yours yet, the names are identical, though.
They're actually in the World Category of styles.
Here is the list:
1 MARIACHI CUMBIA ritmo de m�sica con Mariachi
12 MARIACHI POLKA m�sica de Mariachi.
17 MARIACHI VALZ Muy popular el Valz con Mariachi
21 BOLERO RANCHERO Uno de los generos m�s rom�nticos y populares
