If you would like to make a playlist based on the content on the folder on your droid, just open a terminal, go to the folder where the music is and run
$ls | sort | grep mp3 > "$(basename "$(pwd)")".m3u
and magically you have the playlist..
which looks like this:
04 - Pennywise - Fuck authority.ofn.mp3
07 - A Perfect Government.mp3
07 - Pearl Jam - Do The Evolution.mp3
13 - Goldfinger - 99 Red Balloons .mp3
Nirvana - 03 - Come As You Are.mp3
Oasis - Live Forever.mp3
Offspring - Smash - 05 - Genocide.mp3
System Of A Down - Aeralis.mp3
System Of A Down - Spiders.mp3
03 Whatever Happened to My Rock 'N Roll.wma
the last one is a wma, and if you don’t have time/will to convert it to mp3 can be added with:
$ls | sort | grep wma >> "$(basename "$(pwd)")".m3u
