Before you send me any mails complaining or telling me that I've copied something wrong, I'll say that yes, there are various albums called "Joan Manuel Serrat" and that also yes, there are three albums called "Joan Manuel Serrat" in the same year, it's not a mistake, that's the way it is. 

The songs in Catalan have their respective translations to Spanish and I'm doing the English translations for them as well. In each album you'll see that below the original list you have a list with the same songs in Spanish, and under that the list in English.
