Android Playlist folder

I have a simple question that I may just need a different app. But, I am using poweramp to play flac playlists and the issue is that I cant find a way or another app to make playlist folders. Eg I have several 8 playlist of audiobooks from one author. Instead of seeing all 8 in addition to all the other playlists I have, I would like to create a playlist folder with the authors name. within this folder will be the other playlists. I tried searching but there does not seem to be an app to do this. Itunes does this easily and syncs it to any idevice as well.
Answer #1
None of these are by me, but by others from the source below
Easiest Method:
1. Use Windows Explorer to find your Music folder on your device and create another folder next to it called 'Playlists' if there is not already one there.
2. Create a file in the Playlists folder with the name of the playlist you want with the extension '.pla', like dance.pla. You can do this by creating a playlist in media player, drag it to your device on the left and click 'Start Sync'. Or copy an existing playlist file and rename it.
3. Now double click on the .pla file and you will see a tab called 'References'.
4. Drag your music files into that References area. You will see the new playlist in your device after you click the OK button.
Another method w/mp3s
What I did was 1.)mount the droid manually
2.)dragged the desired .mp3(s) to the the device
3.)since i already had the playlists made up on itunes i just right clicked on the name of the playlist and hit export
4.)chose the file extension .m3u
5.)once the .m3u was created, dragged the .m3u to the droid and it shows up under playlists in the android music app
I like this method bc it doesn't require any software other than itunes
