music is an intellectual aesthetic pleasure that I find at odds with the more tactile aesthetic pleasure of making turns on snow.
the few times I've listened to a .mp3 player while skiing, I've found that my listening brain tries to be choreographer to my skiing body, and with poor results.
perhaps I should explain that I'm not any kind of dancer, never have been and hopefully, never will be one.
oddly enough, I can ride my MTB with music. typically I listen to electronica variants for long fire road climbs, and mid-tempo flowy stuff for descending.
a rhythmic descending song favorite of mine is "My Mathematical Mind," by Spoon, on their latest album. Jack Straw done hooked me up there. thankee bro.
