For me, I'm a Philly cat (of a certain age...Let's just say that I was right there when Will Smith cut his teeth as a member of the Fantabulous Four in Wynnefield/West Philly) and if I had to pick one joint that for me sums up hip hop, I gotta go with Three Times Dope, "The Greatest Man Alive". Classic Philly Hip-Hop, that takes me right back to when I was already heads over heels in love with the music. STILL bangs in the whip too! It encapsulates trully Philly steez, and that hustla (Hilltop!) mentality. There are certainly others, (Schooly's Saturday Night is riiight there) but for me that's as good as it gets.
