Two singles, "Ha" and "Back That Azz Up" became hip hop hits in the United States. "Back That Azz Up" peaked at #19 on the Billboard Hot 100 along with "Ha" which peaked at #68 on the hot 100. "Follow Me Now" was also a single, but did not catch on as the other two did. The album peaked at #2 on Billboard's Top R&B/Hip Hop Albums and at #9 on the Billboard 200 in 1999. It also went to claim the number-one position on the Top R&B/Hip Hop Albums chart on the Billboard Year-End chart for 1999. As a single, "Back That Azz Up" was released, credited, and charted as the more censored "Back That Thang Up". Also the album features a bonus remix of the single "Ha" with New York rapper Jay-Z, the only guest appearance outside of Cash Money. As of 2013, 400 Degreez has sold over 5 million copies worldwide. The album won R&B Album Of The Year at the 1999 Billboard Music Awards.
