Some mp3 players can sort music to play in the configured order. But others can only sort it on date-created criteria. If you have a folder of music (e.g. mymusic) which defines traks order by name (e.g. 01 Music1.mp3 , 02 Music2.mpr, 03 ... etc) you can use next python script to resort it:

resort_date_by_name.py

To run it you need python (python.org). If you install it the first time not forgot to mark in the installer option to add it to the system PATH.

Usage from the console:

$ python resort_date_by_name.py mymusic
