Yes, me too... I can't watch cable news, can't listen to the radio. I sit at the computer and play mindless games like breakout or check in here.
If you want to listen to some mournful music while on the computer (as long as you have audio going), here's a link to The Mansions of the Lord, which was the music played at Ronald Reagan's funeral. It seems to fit the mood for me right now.
It goes on and on, just keep listening even when it seems to end:
