Can't play .m3u playlists?

[JMullins]

I think the problem is because of the structure of the m3u file. It will look like:
#EXTM3U
#EXTINF:293,Armik - Gypsy Flame
\\Media\Music\CDs\Armik\Gypsy Flame\01 Gypsy Flame.mp3

Notice that it give a complete path to the music file (in this case the network path). I suspect that you will need to point it to the files on your device for it to work.
