How to play all songs except classical and movie soundtrack music using the Music app on an iPhone?
Solution 1:
You can use an app like SmartPlaylist to create smart playlists on your device.
You can also create a smart playlist on a computer in iTunes then sync it to your phone. Even though you can't create smart playlists on the device, they do still update automatically as new music is added to the device. No manual maintenance is needed.
