After an invitation-only Beta, Google finally unveiled the much-anticipated digital music store "Google Music" to public on Wednesday. The online music store will be competing with existing giants like Amazon and Apple, users will be able to buy songs costing somewhere between $0.69 and $1.29 through the Android Market - to gain the initial traction Google will be offering one song free daily to it's costumers.

The Google Music intro-tour website is a must-watch letting users enjoy the superb interactive, animated and musical tour introducing visitors to the new service.

Google Music Beta launch yesterday accompanied the release of "Google’s Music 3.0 Android App", once again the app download is restricted to American users and users from other countries are shown error "This item cannot be installed on your device's country" blocking the installation. Luckily XDA dev's have ripped the com.google.android.music-1.apk making it available for free public downloading which is installable on all android devices, bypassing the country limitation.
