National anthems

Would be a cool touch at the end of the race for the winners ( players ) national anthem to play, 

Or you could have the drivers anthem followed by the team owners... I dont know how much it take to add this... though even a National flag selection on our profiles would be cool.

On what, a flag?
Besides, the anthems are associated with the flags so it’s not like anyone has to pay for them
