Hey,
In modern hip hop production:
1. 36.6 seconds of some pad while the rapper says stuff like '...uh, UUGGGHH, watchew lookin' at NIGGA killa etc....'
2. 456 measures of a 4-beat loop programmed on the MPC 2000. The better producers use 8 and sometimes 16 beat loops.
3. A 2 minute skit involving the rapper's friends, some 'ho's' and a cell-phone. And an SUV.
4. Repeat step 1.
: )
