What is the perfect Pandora station?

I recently discovered that Janelle Monae as an artist station on Pandora  pretty much makes the perfect station for my tastes. Her music is pretty eclectic, so the station ends up playing really good music from several genres: dance, rock, hip hop, soul, R&B... In the past half hour they've played Santigold, Stevie Wonder, Kid Cudi, La Roux, and Jill Scott.

So my question is: have you found an artist or song that makes for the perfect Pandora station? Why do you think it works so well?
