There are many events in rap history that are either unknown or forgotten, from album releases to deaths to random ass events most of us can't even recall. As an attempt to remember those moments, Complex will share an event that helped shape hip-hop in a sometimes minor, sometimes major way. Join us as we look back on This Day in Rap History.

February 12, 2009

On February 12, 2009, Eminem's Dr. Dre and 50 Cent assisted "Crack A Bottle" set a new record for opening week download sales at 418,000 copies. The song broke a record  previously set by T.I. and Rihanna's "Live Your Life." The song shot to No. 1 on the Billboard Hot 100, making it the highest charting single off Em's comeback album, Relapse. The song went on to win the 2010 Grammy for Best Rap Performance by a Duo or Group.
