Another study to prove commonsense?
I think general there's a connection, but... I wonder how scientific the study was. A scientific measurement of "lazy?" And in general people who like disco music are on the lazy side? Seems like a bit of a stretch to connect things like that. And I would think it's hard to do a study like that, even though I think it's kind of commonsense that what you like in music matches your personality. I'm sure there are plenty of exceptions. Shy people like classical? I'm sure I'll make some error in logic if things are broken down that simply. There are plenty of arrogant, outgoing people in classical music. Just think of the divas, soloists, and first-chair players. Though that's on the performing side.
Interesting nonetheless.
