Here's a thought...Why did I never think of this before?
I've been having trouble focusing while at work and actually having to do some number crunching and thinking. I work in an open office right now and this morning it was particularly noisy and distracting. So, I put on my headphones and put on some classical music on pandora. My other stations I've had set up before were still too distracting, but classical music was enough noise to help me ignore the other noise around me, but not too distracting.
I guess I've always thought of pandora as more current music, but it's got classical as well. Why had I never thought of this before?
