Interesting activity. My plays depend entirely on my mood. If I’m driving, I want upbeat extremely energetic stuff, like “Highway Star” or “Speed King” or “Welcome to the Pleasuredome.” If I’m just toodling around and want peace, I put on Dave Brubeck Quartet. If I want spiritual uplift, Michael W. Smith or the “WOW Christian Greatest Hits of 2003.”
And if I’m feeling suicidal, Depeche MOde.
Exactly. Maybe the play frequencies on your playlist will tell you how much time you’ve spent in each mood/condition over the years!
