The exact submission address or form is on your sheet, not on this page. That is deliberate: a station that publishes an address for artists should not have it republished where it can be harvested.
Rotation's free sheet is U.S. radio: 1363 stations, none of which has a rule about what country you are in. A UK artist can use it as it stands.
