Important Notes - Using the system default engine allows playback of DRM-protected and online music, but some features will be restricted. By default, the system engine is disabled. - Changing the playback speed, changing the pitch, using the equalizer, or MIDI file playback will increase battery consumption. - Settings cannot be fully restored from backups, and exporting playlists to other devices is not supported. I recommend that you use the system music app's playlists. This app and its description contain automatically generated text. This app does not contain any songs.
