build your own Sound Voltex soundtrack because Konami won't make one for some reason

sdvx-gst.rb

# build your own SDVX soundtrack
# grabs all the YouTube URLs for konemi's SDVX lineouts
# and makes a shell script that downloads them and turns them to MP3s
#
# requires: youtube-dl, ffmpeg
# usage: ruby sdvx-gst.rb > sdvx-gst.sh
#
# hey konami, it's kind of dumb we can't pay you to get these songs, just sayin'
