Speaking of finding new artists via Pandora...
Pandora introduced me to Cary Brothers, from his MySpace page I found Joshua Radin and Jason Kanakis (really enjoy his guitar work), the two of them led me to Rachael Yamagata and Schuyler Fisk.
Here is a taste of Schuyler's stuff, I have been playing several of these songs over and over..... (wish she would release a CD)
