Samsung launched its Music Hub service in the U.S. on Tuesday. It's an effort to capture some of the buzz around Spotify with a feature that combines a cloud music locker, unlimited song streaming, a radio player and a music store.

All that costs $10 a month, although song purchases are charged separately. The catch: you need a Samsung Galaxy S III phone to use it.

The U.S. launch comes with a 30-day free trial period. Music Hub was introduced in Germany, France, Spain, Italy and Britain in May.

The service offers covers a range of services not available now from a single provider.
