What is ti r kelly trouble man?

It seems like there is a misunderstanding in your question. "Trouble Man" is not a song by R. Kelly, but rather a track by American singer-songwriter Marvin Gaye. It was released in 1972 as the soundtrack to the film of the same name. The song is a soulful, introspective track that reflects on the struggles and challenges of life.

If you are referring to a different song by R. Kelly called "Trouble Man," please provide more context so I can offer more accurate information.
