# Now, you may call an API to fetch the lyrics for this track,
#
# curl \
#   --get \
#   --silent \
#   --data-urlencode "track_name=$track_name" \
#   --data-urlencode "artist_name=$artist_name" \
#   --data-urlencode "album_name=$album_name" \
#   --data-urlencode "duration=$duration" \
#   "$URL"
#
# or simply print a template to write the lyrics yourself:
printf "Lyrics '%s' by '%s' (album: %s, duration: %s seconds)\n" "$track_name" "$artist_name" "$album_name" "$duration"
