This one is fun. I looked up the names of eight or nine (if you consider Hindi and Urdu to be two different languages) South Asian languages on YouTube. And the results are amusing.
Punjabi lives up to its reputation. The top results are all popular soundtracks. Searching for Tamil, Telugu, Gujarati and other languages brings you clips from popular movies, TV serials or some stand-up comedy. Hindi is the sole exception.
All the top results are adult movies when you search keyword "Hindi." It seems the Hindi heartland can be rechristened either "Sexistan" or something like that.
Finally, before I will leave it on philosophers to mull over it. Anyway, it will be useless to draw conclusion on this data alone. I do not know how YouTube produces results, and I have no inclination to find it out--at least not right now.
