about the movie "Ray"

I did’nt know about Ray Charles at all until I watched this movie last week. I think his music is very great and makes us fun, but it was not good that he got lovers except for his wife! I worry whether he could separate from his lovers and quit a drug or not. By the way, I could not understand why people got angry when Ray played gospel music. I want to listen to his music more, so I’m looking forward to watching the movie tomorrow.
