Download csv song collection using tinysong

gistfile1.rb

# This script reads a csv file with song name and 
# artist name in order to download them.
# This csv can be generated using for example http://groovebackup.com/
# if your collection is hosted on Grooveshark.

# Before running ensure watir-webdriver gems is installed.
# For windows you will also need Chromedriver.exe to be in your PATH.
# Finally the extension GroovesharkDownloader is required.

# Note that this technique is intrusive! 
# You can't use your pc while its working since 
# it opens and closes a lot of windows.

# csv_path = 'songs.csv'
# csv_text = File.read(csv_path)
# csv = CSV.parse(csv_text, headers: true)

# Option 2: (Default)
# 1: Go to groovebackup.com and authorize the app
# 2: Choose either full collection, favorites or a playlist
# 3: As soon as you click on any of the options it will start to download automatically
