Eminem proves that he is the "Rap God" indeed by ruling the Billboard Hot 100 -- The Marshall Mathers LP 2 rapper's hit collaboration with Rihanna, "The Monster," celebrates its fourth week at the No. 1 spot on the chart.

The "Pour It Up" singer's 13th No. 1, and the "Berzerk" rapper's fifth, holds strong at the Hot 100 list. According to Nielsen BDS, "The Monster" racks a fourth week on top of the Radio Songs airplay chart to 136 million in all-format audience impressions (down 7 percent). On Digital Songs list, leading for four weeks, the hit track rebounds 3-2 with 433,000 downloads sold, gaining by 124 percent, and all titles on the 50-position Digital Songs chart gain this week, as consumers redeemed digital gift cards after Christmas, rising by 98 percent in total from the previous week.

While "Monster" falls to No. 2 after a week atop Streaming Songs to 4.7 million U.S. streams (down 38%) and drops 1-2 after six weeks at No. 1 on the subscription services-based On-Demand Songs chart to 1.6 milion (down 25 percent), it is still sitting at No. 1 on both the Hot R&B/Hip-Hop Songs and Rap Songs charts for its ninth week. It leads the Rythmic radio-based list for a fifth week, and Pop Songs and Rap Airplay for a fourth week each, as well.

In addition, the evidently impressive record of the hit track marks Rihanna's 51st career week at the summit, pushing her past Boyz II Men (50 weeks) for the third-most weeks spent at No. 1 in the chart's 55-year history.
