I was surfing MSN.com earlier this week and stumbled upon a short article, written mostly tongue-in-cheek, about what your musical tastes say about your personality, especially in regards to relationships.
A few highlights:
Apparently, if you're a guy and you listen to heavy metal, you may have some problems with anger, as well as a tendency to be aggressive in bed (a trait your partner may find exciting...or not). Women who are fans of '70s hair bands supposedly have aging and body-image issues. The country music lovers are thought to be "good" people, often from the Heartland, who are loyal, honest...and, also, boring with a potential for prudishness. The classical music listeners are believed to be extremely intelligent. (Note: The article's author was a self-confessed classical fan.)
There was more, but those were the ones that stuck with me.
I've searched for--but couldn't find--the original post. I'll keep looking. In the meantime, here is a British (and somewhat different) take on the same theme: http://www.timesonline.co.uk/tol/news/uk/article788601.ece .
