This is why I like listening to NPR: in a promo for an upcoming episode of Marketplace that covers government regulation, they used Warren G's classic "Regulate" for the background music. For serious.
It's like having Snoop Dogg introduce the NewsHour with Jim Lehrer.

Seriously - NPR rocks. I listen to WUTC Chattanooga, TN in the morning from 8-10am, then WNYC until noon, then WPVM Asvhille, NC.
I listen to the Marketplace podcast and they really do play some pretty 'hip' music in their breaks.
