vgm_stat
vgm_stat is a command line tool for making a list of track names, lengths, and numbers for a pack's text file.
Usage
vgm_stat A_Game_Name.m3u
For pack submissions and update corrections, you must give vgm_stat an M3U playlist. This is needed to make vgm_stat output track numbers, required for the text file's track list.
If however you just want a list for personal use, vgm_stat can also accept a folder.
