Which foreign language would you love to learn and what would be your motivation behind it?

We are building a language learning platform for learners who feel disengaged with the traditional learning methods (self-learning apps/online tutorials), who want to learn a language through application-based interaction, improve fluency and feel the cultural immersion.
