When Google music beta came out I wasn't too excited about the whole thing but I know that Google products are of the greatest standard so I wanted to give it a shot, however I was sad to see that the beta is only available in the USA.
I thought about how I could fix this and found that a simple proxy from within the USA would allow you to register (and get approved) and after the registration you will be able to log in without going through the proxy every again. The way I did this was by referring to my article on Megavideo Bypassing which shows you how to find a USA shell account and forward traffic in a clean way.

I assume that any type of proxy method would work but I just used my way. I haven't really played around with Google music beta yet but I thought all of my fellow Canadians would like to know that it can be done! If you want an invite I have 4 left so leave me a comment!
Edit: I have given two invitations to people that have commented and what I propose now is a sort of pay-it-forward thing. Once I run out of invites perhaps those that received one could send one to another commenter.
