I know that this is kind of hard to believe, but ...

... I think that I might do better at work watching videos over listening to music. When I'm watching my iPod, most especially if I'm watching something that I've seen before, I mostly listen to it, occasionally glancing down at the screen laying next to my keyboard. When I'm listening to music, most especially to a song with lyrics, one that I really like, or even a classical or jazz instrumental that I really like, I tend to sing or hum along with it. If it's really catchy, I'll almost dance along with it in my chair. I put more mental concentration into listening to the songs than I do semi-watching a movie or TV show, even when I know what I'm watching well enough to quote the lines. Interesting ...
