You should be more specific with your questions about genre of music, because of Hip Hop, New York's numbers would be through the roof. With their combination of R&B, and rap, it would probably be a runaway.
As far as R&B goes, it's probably neck & neck between Philly, and Detroit, and I'd probably give a slight edge to Philly.
Now as far as overall hits go, that title belongs to Nashville, and the many country western hits that have littered the charts over the years. :emlaugh:
Told you to specify.
NICE
