As with much of today's Google Music announcement, the new Artist Hub service is also subject to some regional limitations at present.
At launch, to upload and publish music through the Artist Hub, you must be a resident of the United States and its territories. The full list is as follows:
- The 50 United States and the District of Columbia
- American Samoa
- Northern Mariana Islands (CNMI)
- U.S. Virgin Islands
- Puerto Rico
- Republic of the Marshall Islands (RMI)
- Federated States of Micronesia (FSM)
No word as yet on if or when the service may be opening up to the rest of the world, so we're all going to have to sit tight.
