your emotional state influence the kind of music you listen?

I agree with you, music is all about emotion. Even music without vocals. If you are feeling happy and then listen to two hours of sad music, Im almost 100% sure you wont be so happy after those 3 hours. : )

I love to listen to Pearl Jam, but whenever I do it makes me really, really depressed! So even though I like their music, I try to stay away from all of their music. Even their new, inspirational song "The Fixer" makes me think of all of their other, not so good ones. So I only like to listen to their music after I break up with a guy!

most definitely. i find that when i am excited or feel really good i like to listen to upbeat music like rock or jazz and when i am tired i like to listen to classical and when i am feeling nostalgic, i like to listen to big band.

This is hard for most people to understand, but I do not much listen to music. In my community we are fortunate to has a free service from the cable TV called Music Choice that has lovely nonstop soundtracks of classical, light classical, easy listening, show tunes, and all of those other genres (except I am not sure about the anime--that we might not have), and I guess if I were sad or bored or just had time on my hands I would turn it on and listen, but then I would not be doing something else and using the music as a background. I would be 100% listening to the music, and for some reason I just don't seem to have time to do that a whole lot, as there are so many interesting places to go and things to do. I guess I am just more visual and than auditory. I do however, like to sit down at the keyboard and try to play music from time to time. If I did more listening I would probably be better at playing, too.
