Eminem signed for the record label Interscope Records in 1998. He released his first major studio album, "The Slim Shady LP", a year later in February 1999. It was based on productions by Dr. Dre. "Billboard" praised the album as "light years ahead of the material he had written before". It went on to be one of the most popular albums of 1999, and it achieved three times platinum in the United States before the end of the year. The album's popularity also brought controversy around much of the albums lyrics. In '97 Bonnie and Clyde" he describes a trip with his newborn daughter, Hailie, when he discards his wife's body, and in another song called "Guilty Conscience", it ends with persuading a man to kill his wife and his lover. "Guilty Conscience" marked the beginning of the friendship and musical bond between Dr. Dre and Eminem. The two would later collaborate on a lot of hit songs, including "Forgot About Dre" and "What's the Difference" from Dr. Dre's album "2001", "Bitch Please II" from "The Marshall Mathers LP", "Say What You Say" from "The Eminem Show", "Old Time's Sake" and "Crack a Bottle" from "Relapse" and "I Need a Doctor" and "Die Hard" from Dr. Dre's "Detox". Dr. Dre would appear to have at least one guest appearance on all of Eminem's studio albums for Aftermath Entertainment. The album has now achieved 4x platinum in the US. With this release, Eminem was accused of imitating the style and word choice of underground rapper Cage.
