How do I make \n actually work in my output? At the moment it just writes it all in 1 long block. Thanks for any help

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
@new = ''
playlist_name = gets.chomp + '.m3u'

music.each do |z|

File.open playlist_name, 'w' do |f|
  f.write @new
end
