Google is launching a new service that will let users store their music remotely and access them from any compatible device, including mobile phones, tablets and computers.

Google Inc. said Tuesday the service will be available by invitation only starting Tuesday. It says the service, "Music Beta by Google" will be free at first while it is being tested. It did not say what it plans to charge later.

Google says users will be able to store up to 20,000 songs.

The offering competes with Amazon's cloud-based music service. This lets you play songs you've uploaded on your computer or on a smartphone that runs Google's Android. Apple Inc. is also believed to be working on a similar service.
