From Pine's Learn to Program. This program creates a music playlist in the specified directory.

playlist_creator.rb

directory = '/Users/kevinbuchanan/Music'
Dir.chdir directory

playlist = {}

while true
  puts 'Enter a song name to add to the playlist: (Press enter when done)'

  song = gets.chomp

  if song != ''
    file = Dir.glob("**/*#{song}*.???")
    if !file.empty?
      playlist[song] = file
      puts "#{song} was added to the playlist."
    else
      puts "#{song} was not found."
    end
  else
    break
  end
  
end

puts "What would you like to title the playlist? (No Spaces)"

title = gets.chomp

File.open "#{title}.m3u", 'w' do |f|
  playlist.values.flatten.each {|song| f.write song + "\n"}
end

puts "Your playlist has been created here: #{directory}"

This actually returns all songs containing the word that is entered when searching. I need to figure out how to return only exact matches.
