Using Pandora or Google's Music outside U.S.

If you're in Germany, UK, Austria, Australia, France, Italy, Russia, Japan, Spain or wherever except the United States, you can't use services like Pandora or the newly launched Music (Beta) service from Google. Also some YouTube content might be blocked in your country.
If you are eligible to access these services and all those YouTube videos, you could try Tor
Specifying an US located server in the torrc configuration file as the ExitNode and setting localhost:8118 in your browser as your proxy for HTTP and HTTPS, will enable you to access all those services. You can find an US located server using Tor's resp. Vidalia's "View the Network" button.
