[defective]

I am the same as you, as far as focusing on finance and tech. I think there are reasons why these topics are far less stressful or depressing: Tech news and reviews are exciting when they are good, and irrelevant when they are bad. If something gets some bed press, you simply don't buy! Also the tone is often nice, probably because tech reviewers have a pretty good job. They get to play with new things all the time and get paid.

Finance is usually upbeat as well -- now, I get most of my news from Bloomberg, if that matters. But since hedge funds can't advertise, literally everyone in the financial news chain benefits from the stock market going up. This may tend to color reports to the positive, making for a happier listening experience. Giving everyone the benefit of the doubt that they would ever "color" a story, then even in difficult times, the focus is on investment opportunities and interviews are always with those doing well. Ever since I switched to Bloomberg news radio and a focus on online tech news, I feel like I can bear to live in the world again!
