I have been in my office all morning, catching up on recommendation letters and the like. My labors have been aided by Pandora Radio, part of the wonderfully named Radio Genome Project. You tell them what kind of music you like, and they make a station for you. They find music like that, and you tell them if you want to add the new one or not. That judgment, in turn, generates more connections. This morning I have been listening to Allison Krauss Radio. This is becoming a large collection of my favorite genre, what my wife calls "whiny white chicks." At the moment I am listening to Neko Case.
For physical activity, like cleaning my desk and moving furniture, there is Bruce Springsteen Radio.
And its free.
