Rdio, a new music streaming service, is now available to anyone in the US and Canada.
Previously only available by invitation as a private beta version, the service is now accessible from both Windows-based PCs and Mac computers, according to its developers Janus Friis and Niklas Zennström, the co-founders of Skype and Kaazaa.
The pair said that there are also applications for use on Apple's iOS platform, Google's Android OS and Research in Motion's BlackBerry OS, allowing users to access the service from their smartphones.
Rdio integrates with major social networking platforms, allowing users to follow others' playlists, or suggest music to friends based on their profile preferences.
The service will offer users an unlimited music library for a standard monthly fee of $9.99, which allows users to stream music from their smartphones and enables them to transfer songs.
The company said that those who want to only access the browser-based version of the service from their desktops and laptop will pay $4.99.
