I would think that the Gallente would have an anthem more like the Spanish one.
Where the singing is done by going 'lol' with the tune.
Amarrians probably do not have a national anthem, the nation and the religion are inseparable.
Probably one of the more common hymns could be used in place of one, but a regular amarrian probably knows oodles of them.
Minnies?
Because of the Gallente influence they would probably have something along the lines of Shakiras 'Waka waka'.
State would probably have none, just anthems for the different corporations...
