Streaming music is one of the best ways to explore new artists, albums, and entire genres. Without risking anything, users can connect and listen to something new. No $13.99 on a CD you aren’t sure if you will like. No $1.99 fee for downloading a song a friend’s brother’s wife said you would like.

Insert Rdio here.

Rdio is one such low-risk streaming service. For a small subscription fee, users can have access to millions of artists, albums, and genres. Rdio attended the Mobile Acceleration Week event in San Francisco last fall in order to begin building a Windows Phone 7 application.

Rdio built a music service app that takes the work out of deciding what to play next. Users can follow friends and people with great taste in music, get inspired by what they’re playing, and listen to their playlists. With Rdio’s mobile apps, music on a computer and mobile phone is finally connected without needing a cable. Collections and playlists are instantly updated and you can sync music and listen, even when a user is offline.The app can be found on Marketplace, and boasts a large download number.

Last week, Rdio attended the annual Marché International du Disque et de l’Edition Musicale (MIDEM) event in France and made quite a splash. Scott Bagby, Rdio’s head of strategic partnership, gave a stellar interview about the company’s recent aggressive expansion into Germany and Australia. According to Bagby, 2012 will bring expansion into Asia, Europe, and South America. Who knows where Rdio will expand to next.
