не хочет(

как вариант дай мне вывод ls А я дам скрипт который все сделает

ls сделать в папке с mp3?

да

root@D5803:/sdcard/VK Coffee # ls
CraSET - Forever.mp3
Sigmafly - Tides.mp3
Vacant - 3 years of _Just a chill room_ Mix.mp3

это все?

но эти ж файлы там всегда разными будут

ну пока там 3 файла а так это всё динамически меняться будет

тогда только с помощью busybox

я понял кароче надо sed ставить
