I don't listen to much rap but i came across this song and apparently figured it out. All of the low notes are F5 and it is played at random times E|-| B|-| G|-| D|3| A|3| E|1| and after he says "don't quote me boy cause I ain't said shit" E|------------------------------| B|------------------------------| G|------------------------------| D|5-5-8----5-5-3---5-5-8---5x5-3| A|------------------------------| E|------------------------------| If I ever listen to this song again I will try to find those high notes.
