I like the title a lot. To me, Spanish Just Because sounds like a fun place to visit to learn and play with the Spanish language. "Just because" is a widely used phrase in English, in my opinion, particularly for children and for adults when we are feeling playful. The meaning, often, seems to me to be something like "I like this and I want to do it, and I have no special reason or rational explanation why that I want to share. So just accept it :) "
