Dr. Dre feat. Eminem & Skylar Grey - I Need a Doctor

Once again, this is why Dre is well the DR! Guy had it back in the day and he has it today. Eminem has cleaned himself up and returned to rule the rap scene. He truly is the best rapper in the game today. Then we come to relative newcomer Sklyar Grey who sings the chorus. Didn't know the name but knew the work. She sang the original demo for Love the Way you Lie II. Not sure if she wrote it but she sang it and it is right up there with Rhianna. Demo below. Of course a nice mastered version would sound better but you can hear the talent.
