I knew a couple of older, non-traditional Hmong students at my university who simply didn't listen to music. Didn't have a favorite style, didn't ever listen to music while they worked, if a radio was on and they were alone, they'd turn it off.

It must have been a combination of age and culture, because all the other Hmong students I knew (we had a large Hmong student population) who were my age were really into music.
