You can listen Hindi movies songs in your marriages and parties, people love to dance on that track. The Hindi movie songs is usually mixture of Hindi and Urdu words. If you go in every state of India you can find the Hindi accent and words will be change for example Gujarati mix there words, and if you hear Marathi people they speak Hindi in different ways, same as you can find Urdu in your different states of Pakistan. It's not big thing. The National Geography and any other channel also used Hindi language, it's not limited. In India we have many languages I think you know that. If you saw only one Hindi movie and may be few National or discovery channel, So its hard to understand the difference for people like you and it's hard for you to understand the Hindi language not for us, So leave it.
