Musically, "I Need a Doctor" is predominantly a rap song, backed by a "spacey," drum-heavy production, with extra piano keys featured in the introduction and the chorus. Lyrically, the song is largely about Dr. Dre and Eminem's close friendship, and how they have often needed and inspired each other in the past.
Due to the song being leaked onto the Internet several months in advance to its release, it was a significant commercial success on its official release, particularly in the United States, where it peaked at number 4 on the Billboard Hot 100, becoming Dr. Dre's second highest peaking song on the chart ever, and also peaking in the upper regions of many national charts. As of October 2011, it has sold over 2,206,000 digital copies in the United States alone, making it Dr. Dre's first song to reach the landmark.
