Steps I took:
1) go to http://www.daveproxy.co.uk/
2) enter the following URL: https://www.spotify.com/en/get-started/
3) Enter invitation code: SJySMbb5pUEVyq2i
4) Code will fail (Click download) near code
5) Download application
6) Click signup from that download application page (will no longer ask for invitation code)
7) Sign up using UK postal code check http://www.postcodesearch.org.uk/
8)Install application and use new account.
My next step I want to take is to pay for premium subscription with paypal and run the android app.
My problem: US app store does not have the Spotify App available.
