Basically this is a hack that will allow you to purchase your subscription at the Philippine's pricing. After being pissed off at paying $2/month more than the US per month I found out this method. You can choose what to pay by using a different country.
Step 1: Signup to Rdio
Step 2: Install hola.org free
Step 3: Set country to Indonesia (Thanks to sunilkimm) or Philippines.
Step 4: Go to subscribe and it will show you the price in that country.For me it was 99 Pesos. https://i.imgur.com/Mw89lh4.png
Step 5: Subscribe. (I used it on a Debit card, make sure you select Philippines/Indonesia and use a random postcode) DO NOT SET COUNTRY TO AUSTRALIA AT ANY STAGE!
Optional: Use it in conjunction with a spare tiny debit card account. I used it with my Ing Direct free $50.
You won't need to use Hola again whilst playing the music as the Rdio pricing locks in since people travel overseas everyday and they can't randomly change the price.
