# M3U to Samsung SMPL Playlist Converter
# Written by ChatGPT

# This script converts an M3U playlist file to the Samsung SMPL format. It reads an M3U file, extracts file paths,
# and generates a Samsung SMPL JSON file with a "members" array, where each item represents a file from the M3U playlist.
# Samsung SMPL format is old but used in the samsung music app here: https://github.com/AyraHikari/SamsungMusicPort
