Dr. Dre's second album, "2001", released in 1999, was his return to gangsta rap. It was at first called The Chronic 2000 as a sequel to his first album The Chronic, but was changed to 2001 after Death Row released an unrelated album called "Chronic 2000: Still Smokin" in 1999. The album has also been called by fans 'The Chronic 2001' and 'The Chronic 2'. The album featured a lot of guests, including Devin the Dude, Hittman, Snoop Dogg, Xzibit, Nate Dogg and Eminem. The album was really good, charting at number two and has since sold millions of copies. The album included popular hit singles "Still D.R.E." and "Forgot About Dre", both of which Dr. Dre performed on Saturday Night Live in 1999. Dr. Dre won an award for Producer of the Year, in 2000, and joined the Up in Smoke Tour with Eminem, Snoop Dogg, and Ice Cube. In 2001, Dr. Dre was sued a few times.
