Lineage exists in damn near all aspects of life. In family life a father may die leaving his son or daughter to sustain the family name and it's legacy.
Dynasties exist in royalty for thousands of years.
The saying goes that art imitates life, and that's the truth. Even though it seems like yesterday, it was 4 short years ago when the music world lost one of its kings. When I heard that he'd actually died, I was mortified with bone chilling shock because a nigga just knew that he was gonna make it. Hip hop, like any family, was hurt and would never be the same. However, Tupac didn't go without leaving a legacy behind.
