Since May Google Music exists, a cloud music hosting service to upload own music files and to access these files on various devices. The participation happens by an Google account and during the current beta phase by a request of an invitation. Now Google has launched a further music service to support the use of Google Music by offering music discovery facilities.
The new service Magnifier has a blog style and introduces music by features like song of a day and being available on Google Music. These introduced tracks and those available within a free song archive may be stored by members of Google Music within their accounts to be listened to. For some further information about the new service a page with tips + tricks is available at Magnifier.
