Hip-Hop star Eminem continues to be one of the music industry’s top selling acts, despite an four-year hiatus from the business. After two days in stores, the rapper’s sixth album Relapse is on pace to move over 650,000 copies, making it the year’s best debut thus far. The Shady/Aftermath/Interscope release will easily beat U2’s record setting album Horizon, which sold 480,000 copies when it was released on Interscope in March. Relapse is expected to easily top Billboard’s Top 200 charts next week, giving Eminem his 5th consecutive #1 album.
