Music director A R Rahman, whose compositions in Slumdog Millionaire made him the first Indian to win twin Oscars, is critical of political parties using for a poll campaign the song Jai Ho that he composed for the rags-to-riches drama.

"I was like in the bed, I was dehydrated, exhausted, and then all these things happened, somebody told me these people are using it. I hate politics. I just want people to serve the people. I want governments, whichever government comes in, to be unbiased and say there should be justice in the country and that's my purpose in life," said Rahman.
