Music tastes and personalities

This is an interesting study. The study doesn't account for the changing phases of music and admits that it cannot answer the "a little bit of everything." class.

But, at least there is enough of a correlation that when a music moves you, it could be used as a) a guiding technique to enter a particular mode b) give you indications on what you're feeling and c) potentially help a friend in need.

Oh yeah and the obvious - all those music recommendation algorithms could do a better job too, I guess.
