Is Hindi very difficult to learn?

I know I probably am being a little ambitious with Japanese, Korean, and Mandarin, and wanting to add yet another language to look at for studies, but I just really like this side of the world, and this language captured my attention. But I'm not sure whether or not the one I've heard (in music) is the same dialect, or if there are different dialects.

I will do some research, and make a follow up post. In that post I will tell you if there are many dialects, how many, and which one is more convenient to learn.

Who knows? I might embark on a Hindi learning adventure soon! Well, maybe :)

And you? Have you got an interest in Hindi? Have you studied this language? Is the writing hard?
Tell me in the comments.
