I work in an alternative clothing and music merchandise store and I have the privelage of blasting music out all day. Fortunately as i'm in charge, I get to play music from my collection.
I play bands like The Beguiled, The Cramps, The Staggers, Bloodshot Bill, old school rockabilly and surf every day. Of course, I play the GP Podcasts too and I often get people commenting to me that they like my store because we always play such unusual music and it creates such a cool vibe. And when they ask me, "Hey, who is this band you're playing?", I get a pen and paper and jot down the GP web address and tell them to check us out.
I guess it's not that I "feel the need" to spread the wealth... I'm just lucky enough to play what I want. I think everyone digs savage rock 'n' roll - they just don't know it yet!
