How to Play Music from the Windows 8.1 Start Screen
Click the Start screen’s Music tile.
The Start screen appears when you first turn on your computer. To find it from the desktop, press your keyboard’s Windows key or click the Start button in the desktop’s bottom-left corner.
On a touchscreen, slide your finger inward from any screen’s right edge to summon the Charms bar; then tap the Start icon to return to the Start screen.
The app fills the screen with tiles representing your albums or artists.
Sign in with your Microsoft account or your Xbox Live account, if desired, or ignore the sign-in message. Each time you open the Music app, Microsoft tries to link the Music app with your Microsoft account or Xbox Live account. Because those accounts can be linked to a credit card, you need one of those accounts to buy music.
Don’t want to buy music? The app still lets you listen to your own music, but you’ll see the words Sign In located in the screen’s upper-right corner. If you change your mind and want to buy music, click the words Sign In to sign in with a Microsoft account.
