Ruby script for setting lyrics in iTunes Library tracks

One of the cool features of the iPod Touch and iPhone is that is possible to see the lyrics of a track while it’s playing. The picture bellow shows that.

 

But the problem is that you have to insert the lyrics manually using the iTunes, for each track you have to use the “Get Info” option and then set the track, just like the pictures bellow.

 

That’s a problem, because if you have hundreds of tracks, it will take lots of clicks and time. In order to solve that problem, I created a Ruby script that tries to set lyrics for all the tracks in my iTunes Library.

The script interacts with the iTunes COM components to get all the tracks in my Library, after that, it uses the LyricWiki web service to get the lyrics for each track and set to it.

The script works only on Windows and it’s available in my github repository:

git://github.com/dougfernando/itunes-helper.git

Now, every time I get a new album, all I have to do is to run the script again,  like the following images :

The script code is also bellow:

require 'win32ole'
require 'soap/wsdlDriver' 
require 'iconv'

class ITunesHelper
  def initialize(lyrics_service)
    @itunes = WIN32OLE.new('iTunes.Application')
    @tracks = @itunes.LibraryPlaylist.Tracks
    @lyrics_service = lyrics_service
  end

  def show_all_tracks
    @tracks.each do |track|
      print track.Name() + "\n"
    end
  end

  def set_all_lyrics
    puts "Number of tracks to be analyzed: #{@tracks.count}"
    index = 1
    @tracks.each do |track|
      if self.is_lyrics_empty(track.lyrics)
        lyrics = @lyrics_service.get_lyrics(track.Artist(), track.Name())
        
        if self.is_lyrics_empty(lyrics)
          self.print_track(index, @tracks.count, track, "lyrics WAS NOT found")
        else
          track.lyrics = @lyrics_service.get_lyrics(track.Artist(), track.Name())
          self.print_track(index, @tracks.count, track, "lyrics WAS found and set")
        end
      else
        self.print_track(index, @tracks.count, track, "already had lyrics")
      end
      index = index + 1
    end
  end

  def is_lyrics_empty(lyrics)
    lyrics.empty? or lyrics == "Not found"
  end

  def print_track(index, total, track, result) 
    puts "Track #{index}/#{total}: #{track.Artist()} - #{track.Name()}: #{result}"
  end
end

class LyricsServiceProxy
  def initialize
    @driver = SOAP::WSDLDriverFactory.new("http://lyricwiki.org/server.php?wsdl").create_rpc_driver
    puts "Lyrics web service initialized"
  end

  def get_lyrics(artist, track_name)
    Iconv.iconv("LATIN1", "UTF-8", @driver.getSong(artist, track_name).lyrics).to_s
  end
end

itunesH = ITunesHelper.new(LyricsServiceProxy.new)
itunesH.set_all_lyrics
