Shhhh. Don't tell my wife, Terri, but I fall in love when I hear Italian, or French.
Italian and French are one of the reasons I adore opera. I can't understand the words. When I can't understand the words I focus on the music, the melody, the raw beauty of the orchestra, the synergy between singers and players–something that doesn't happen as much when it's sung in English and I add meaning as a third element.
I could solve the problem by just listening to orchestral music and never be distracted by the lyrics, but it would not be as pleasant to me. I find unintelligible lyrics a bonus–a different genre unto itself–when combined with orchestras.
Ignorance, certainly in this case and for me, truly is bliss.
