Rdio has announced the launch of their operations in two critical markets.

They are now accepting registrations from anyone located in USA and Canada.

The service is free without ads for three days. Users can request for a 10 day extended free trial.

It would generally cost around USD 10 per month for unlimited web and mobile access.

Users also have the option get a web based access only for around USD 5.

Rdio is one of the many streaming music services to arrive in the market.

It faces tremendous competition from existing and upcoming players like Spotify, Pandora, MOG and others.
