This is the ultimate New Playlist Manager and MP3/M4A/FLAC tag Editor.

It has unique features you will not find with other playlist apps.

For those who have the P*amp music player installed, New Playlist Manager allows you to manage your P*amp playlists, backup your Ratings and Times Played (something P*amp cannot do) and even update your mp3/m4a/flac track Ratings tag itself so you will never lose these settings.

To get the maximum from this app, ensure that all your tags are suitably completed.
