Slacker Radio is a wonderful app to listen to music but it is only available to people in the USA, so people outside the states are left out of all the fun. We have a brilliant app on playbook which we really can not use... but i just found a workaround which lets you use slacker along with quite a few other streaming sites restricted to the US.
Register on UnblockUs Inc. - Portal Home, and then set up your router with the dns they provide you with. Mind you this is a paid service where you have to pay around 4.5$ for a month but you have about a week of free trial to test it out.
Happy Listening.
