Today the homie Rain started his 7 Day Theory series. In which he will drop a new freestyle (over a 2pac instrumental) each day leading up to the anniversary of the death of one of hip hop's most beloved fallen soldiers. This series is an OS exclusive I'm pretty sure, which is why I'm jacking their link. September 13th will also be the day that Rain's American Dreamin mixtape drops with the 7 Day Theory freestyles being included as a bonus disc. OS has Rain's thoughts.
