400 Degreez is a hip hop album by New Orleans-based rapper Juvenile, released on November 9, 1998 (see 1998 in music). The album received rave reviews and introduced Juvenile to mainstream hip hop listeners.
Two singles, "Ha" and "Back That Azz Up" became hip hop hits in the United States, although "Back That Azz Up" was the only one that managed to cross over and become a pop hit as well. The album was a #2 hit on Billboard's Top R&B/Hip Hop Albums and peaked at #9 on the Billboard 200. "Follow Me Now" was also a single, but did not catch on as the other two did. As a single, "Back That Azz Up" was released, credited, and charted as the more polite "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.
