You can use WMP 11 to make or edit playlists in m3u format whenever you like.
The format sould be:
Code:
#EXTM3U
#EXTINF:0,02-al_green-just_for_me.mp3
J:\MUSIC\Al Green - Lay It Down (Advance) [2008] - R&B\02-al_green-just_for_me.mp3
#EXTINF:0,03-hellsongs-rock_the_night_kiss_cover-mst.mp3
J:\MUSIC\hellsongs
etc.
In my M6 SL 2.004.6 only works when it starts by the letter of the unit in my OS (strange...). This happens when you save directly the playlist in your desktop not in your meizu
