"I live in Vietnam, I want to Play Slacker Radio"
Slacker Radio is an interactive Internet radio service available in the US and Canada. Listeners can access the service on the web, through mobile apps on multiple smartphones as well as on Slacker Personal Radio Players and other devices. It allows users to create and share customized music stations. Slacker allows users to customize one of their programmed stations (for instance, Top hits) or start with music similar to an artist or song, and then customize that. In April 2009, the service had over 2.4 million songs, organized into over 100 programmed stations and 10,000 artist stations.
However the service is unreachable outside US and Canada. Actually, due to licensing constraints, the contents are limited. Therefore the site has a blocking system that analyzes your IP address. If it turns out that you don't live in the US or Canada (information contained in your IP), your access will be blocked. So how to Play Slacker Radio outside US
