The Rugrats Movie. 1999: Double Up and retirement Mase's second album, Double Up, was released in 1999 on Bad Boy and sold 107,000 copies in its first week, debuting at No. 11 on the US Top 200 chart. In Double Up Mase's lyrics became more aggressive. On April 20, 1999, during an interview with Funkmaster Flex on New York radio station Hot 97, Mase announced his retirement from music to pursue a "calling from God". He claimed he was "leading people, friends, kids and others down a path to hell", stating that he left to find God in his heart and follow him. He said it was time for him to serve God in "his" way, saying rap was not real, and that he wanted to deal with reality and had become unhappy with what he did, no matter how much money it had made him. The same year, Mase enrolled as a freshman at Clark Atlanta University, a historically black college, and began taking classes on August 19. Unlike other freshmen, Mase was permitted to live off campus and commute, but he is said to have downplayed his past as a rapper and stayed fairly low-key while on campus. 2004: Return to music After a five-year hiatus from music, during which he became an ordained minister, Mase made his return to music with Welcome Back in summer 2004. Welcome Back was accompanied by a single of the same name and was released on August 24, 2004, through Bad Boy Records and distributed by Universal Music Group. It debuted at No. 4 in the US, selling 188,000 copies in its first week of release, and eventually went gold, selling 559,000 copies in the United States. The album portrayed Mase's new Christian lifestyle and "cleaner" image. Mase dubbed himself "a Bad Boy gone clean" on the lead single (which samples the Welcome Back Kotter theme song). This new approach had a mixed reception. Although the album was not as big a commercial success as Harlem World, the singles "Welcome Back" and "Breathe, Stretch, Shake" received moderate radio airplay and video play on BET and MTV, with the latter single reaching No. 28 on the US Billboard Hot 100. Both singles were also certified gold by the RIAA. In the mid-2000s, Mase spent time touring and recording with New York hip-hop group G-Unit, and became a mainstay of 50 Cent's public image
