# Find directories in music folder modified in last 240 hours

fd . '/path/to/music/' \
--changed-within "240h" \
--min-depth 2 \
-d 2 \

# Remove any paths containing @ symbol (Synology NAS quirk)
rg -v '@' \

sed "s|/path/to/music/||" \

# Interactive fuzzy selection with multi-select enabled
fzf --multi \

# For each selected directory, find MP3/FLAC files
xargs -I{} fd . "/path/to/music/{}" \
-type f \
\( -iname "*.mp3" -o -iname "*.flac" \) \

# Sort the null-terminated file list
sort -z \

# Convert null bytes to proper newlines using sed
sed 's/\x0/\n/g' > /path/to/playlists/newmusic.m3u

This relies on a music directory that is structured {Artist}/{Album}/{Tracks}. Tested with mpd and ncmpcpp
