As far as rdio is concerned, there is no requirement for a proxy server. They actually allow "US users" to travel abroad and listen to rdio. So, what you need to do is get through registration somehow. That works pretty well if you: a. Have a credit card with a US address b. Can go through Amazon payments with a US zipcode I have a credit card with a US address and therefore was able to sign up with no problems at all. Been using rdio for over a year and really enjoying it :) For those that do not have a card with a US address, it's still possible to get through using one of those pre-paid debit cards/asking an American buddy to help/something else. TLDR; rdio does not do IP based filtering.
