Big Sean's fourth album I Decided had been projected to move 115K sales plus streaming in its first week.
That would be a somewhat disappointing number since his last album Dark Sky Paradise did 173K first week in February of 2015.
However, when everything was added up I Decided ended up moving a much stronger 155,705 SPS, which was easily enough for fist place on this week's album chart.
It's the second straight week a new rap album has burst through its early projections to hit number 1; last week Migos's Culture finished at 121K after only being projected for 75K.
This week Culture ended up doing 61,876, which placed Migos third behind Sean Don and Lady Gaga's 2016 album Joanne. which got a huge Super Bowl bump and re-charted with 67,394.
