How to automatically download songs (mp3) from YouTube using Ruby Script

I asked a friend for some music suggestions, and received a long list of songs. Unsure what to do with it, I wrote a Ruby Script to lookup the songs on YouTube, and download the first link that shows up as an Mp3 file. You can do the same with any list of songs titles.

Pre-requisites:

• Ruby
• RubyGem Selenium-Webdriver

If you already have the above two, you can skip installation and head straight to the script.

Installation:

Ruby

For Windows Users, there’s a handy installer
For OS X ruby is pre-installed. Yay!
Linux users can check this out.

RubyGem Selenium-Webdriver

Now, to download the Selenium Webdriver gem (library), run
gem install selenium-webdriver

Script

Assuming you have a list of songs in a file, replace the song_list_filepath with the path to the list.
Just copy scrape_songs.rb, and run ruby scrape_songs.rb

The script runs the following steps:

• Set Downloads folder to Default location.
• Skip Download dialog box for audio files.
• Set Page Timeout to 30 seconds.
• Open new Firefox window with above profile settings.
• Read song names from a file.
• Look up the song name on Youtube, select first video link.
• Enter video url in a Youtube-Mp3 Converter service.
• Download the song.
• Print song names that might have encountered errors.

To modify the script, you can use this easy cheatsheet for Selenium.
