I've discovered and fell in love with quite a few artists that I'd never heard of because of Pandora! There are always those people who go str8 to the negative and in this particular case his point isn't even a negative for some people-I count myself amongst them!
To aaronwbarker -- It would seem to me that the purpose of Pandora is to use your taste in well-known music to lead you to some less-well-known music. Pandora might even be one small step toward tearing down the corporate homogeneity that controls the recording industry. (One could hope, anyway.) But I guess you could always skip the unfamiliar stuff, if you choose. Personally, I marked Doug Strock as one of my favorites, and hope he posts another album!
