Don't know what to listen to? With Groove, find the perfect playlist for any occasion in just a few taps. Imagine having your own personal DJ. Groove studies your listening habits and creates a wide variety of instant mixes to keep your music fresh. You'll never have to manually create a playlist again. Groove has become an instant hit with music lovers on Apple's App Store. As such, the windows 8 version comes with the same outstanding features in a fresh new design. IMPORTANT: This app plays music files (mp3, m4a and. wma) stored in your Windows Music Library only. DRM protected files (including music from Xbox Music Pass) are not supported. To include content from an SD card to your Windows Music Library, please follow the steps here: http://www.groovemusicapp.com/groove-win8/support-music-library-sdcard. If you don't see some of your music, try switching the "Use Windows indexing" option OFF (in the Preferences section).
