Mine is Tristan da Cunha English.

Could someone help me translate this line? It's from "La Calaca" by Amparo Ochoa:

Mucho cuidado señores
Porque la muerte anda lista
En el panteón de dolores
Ya nos tiene una pocita
Para los compositores
Y uno que otro periodista
Licenciados y doctores
Todos están en la lista

Tuku, tuku, tuki, taka
Qué recanija calaca
Cuando menos lo pensamos
Nos hace estirar la pata
Yo me le escapé una vez
Pero por poco y me atrapa

How would you translate 'Felher' in the following song? "The fault is all mine," or "It's my mistake"?

If you scroll to the bottom of the following link, you can adjust the price of oil to see the likely reactions of Russia, Saudi Arabia, the US, and the EU.

For those of you who can't make out the Cyrillic script, 

Россия = Russia
Саудовская Аравия = Saudi Arabia
США = USA
ЕС = EU

For example, my Brazilian friends tell me that Spanish is the second most studied foreign language in Brazil, while Portuguese is gaining in importance in Argentina.

In the US, Spanish is obviously the most important foreign language. I don't think the label "foreign" even applies here. According to different statistics, 20-30% of New York City's population is Spanish-speaking. I think the actual figures are much higher; I would say that at least 60% of New Yorkers speak Spanish. :) 

As far as popularity goes, I would say that Mandarin Chinese is becoming increasingly popular.

What about your country? Which foreign language is considered important and/or popular?
