I think it is not a big deal because it is utterly trivial.
Someone is going to skate to such-and-such music and has a great program planned? Well, that's nice. No need for cloak and dagger secrecy.
I can second your statement. It's just silly for any skater to adopt a secret approach re: their music. It's unnecessary and most likely, it won't have any impact on the judges.
It certainly wasn't her music choice that got her the gold in Vancouver.
