who was i need a doctor written for
I Need a Doctor Skylar Grey said that she and da Kid came to the studio with the hook and "the track" prepared; [Dre and Eminem] loved it. Eminem had then gone into the back room, and came out two hours later, and said that he was done writing his verses.[3] Grey also said that she was in tears when she heard Eminem's verses for the first time and that da Kid initially proposed featuring Lady Gaga on the hook, but Eminem insisted on having Grey's vocals, and said that they were not taking her voice off the track.[4] In the song Eminem raps two verses about his mentor, thanking Dre for believing in him in his early days and returning the favor, before Dre delivers the song's final verse.[5]
