Sometimes songs are inspired by feelings, sometimes by the events, by the books, by the other songs and sometimes songs are inspired by the celebrities and by the other singers. Celebrities tend to stick to their own kind. With all that VIP partying and hobnobbing, it's no surprise that some stars have managed to influence others in very major ways. Wondering who has inspired who?
