That's a good link, actually. What a great way to becomebilingue , by learning the language and culture through music.when I lived in Albuquerque for five years, the way I learned the amount of Spanish (measly) I do know came from going to see bilingual productions by La Compania de Teatro there, and by listening to music. I think it works so well because music accesses a different side of your brain and cuts through some of the "logic" that barricades your brain.
