Anything you could have civic pride in - music, arts, food, whatever - Philly flat out IGNORES.
Ever notice this town has better food/restaurants than any east coast city not named New York? Ever notice how no one in Philly gives a shit?
Ever notice how Eve is the best female MC not named Jean Grae? Ever notice how no one in Philly gives a shit?
I could go on and on.
It generally works as cats get mad local love initially. Examples: The Roots South St/DYWM days (aka Power 99 used to play their songs), Eve when she first came out, Beans when he first came out, give it about a year and Freeway will sadly face the same fate. Cats used to say "Philly's M. Night Shymalan" - they don't anymore. The TV show they film here (It's Always Sunny...) is seeing the light right now, but probably won't next season.
That's Philadelphia, the city of brotherly lo-hey fuck you! We booed Santa Claus and we'll boo you!
