You should have named it Money. Then this could have been the anthem to your Island! "Here comes the monay! Money money money money money money monaayyy! Ching ching, bling bling, cut the chatter: if you ain't talkin' money then your talking don't matter!" 
Empire River though... hm, I'm getting Mongolian throat singing vibes from that... I'm afraid I cannot suggest a song there...
