I took German from 7th through 10th grade. My dad moved to Germany when I was a child.
2 years of Spanish in college. If you asked me how well I speak Spanish, I'd say "muy bueno."
I've done a lot of independent study in Japanese, (and my wife and kids speak Japanese,) so I'm pretty good at that. I have a couple of albums in Japanese with my Scott & Rivers project. I also have a Japanese Twitter account, @RiversCuomoJPN.
Between my Spanish studies and my many hours of listening to Italian opera, I have a feel for Italian.
When I'm on tour in foreign countries, I do Duolingo for that country's language.
