As a music library, it lets users browse and play music as well as create and manage playlists. Any music and playlists from Groove Music will also automatically shift to the Media Player, which replaces the Groove Music app. There's also a dedicated playback view that displays album art in the full screen and mini player mode.
At some point the new Media Player app may replace the legacy Windows Media Player app currently on Windows 11. However, Microsoft says the legacy music app will continue to be available in Windows Tools. Also, now that video is combined with music, it doesn't require the standalone Movies & TV app.
Microsoft hasn't clarified when the Media Player app will be available to general users and notes that during testing with Insiders there are some issues preventing playback from network locations. There are also a few glitches affecting editing album metadata, sorting library content with accented characters, and UI elements disobeying the user's app theme preference.
