English names in Hindi movies

This one thing I fail to understand. What reason could possibly the writers have to give english names? Why do we have Sandra, Frank, Jim, Sarah, David etc.? Why can't we have names like Vijay, Rakhi etc. like we used to have? Have we all of a sudden forgot how to pronounce Indian names?

Could any one please tell me the reason?

Also, now Holi songs are in english? DO ME A FAVOR, LETS PLAY HOLI.... what nonsense... if these people have run out of ideas for holi songs, then do not put holi songs.... but please don't put garbage..
