Music Moods

I usually have Pandora free internet radio open and playing music whenever I'm working in my office or at home. The type of music that I play depends on my mood and energy level. Right now I have update music by Fun playing. Sometimes it's a bit more strange, like Janelle Monae. If I'm trying to shake a sad mood, or if it's really grey outside, I'll usually play Here Comes the Sun by the Beatles. If I'm angry, I'll try OK Go or Mary J. Blige to help me release energy.  If I really need to concentrate on what I'm doing, I find that instrumental music, like Mozart, helps me helps me focus on my work instead of singing along.

What kind of music do you like to listen to? Does it change depending on your mood?
