`ls -1 *.flac`.split(/\n/).each do |flac|
  filename = flac.gsub("flac", "mp3")
  `flac -d -c "#{flac}" | lame - converted/"#{filename}"`

  Mp3Info.open("converted/#{filename}") do |mp3|
    mp3.tag.title = filename[16..-5]
    mp3.tag.artist = "Artist"
    mp3.tag.album = "Album"
    mp3.tag.tracknum = filename[0, 2].to_i
  end
