using ruby-mp3info to fix artist names in mp3 tags

gistfile1.rb

# I always manage to end up with different capitalizations on artist names, 
# which causes some mp3 players to see them as different artists. 
# So I use ruby-mp3info to rename them
#   gem install ruby-mp3info

require 'rubygems'
require 'ruby-mp3info'
# in the directory of the artist, with albums as subdirectories (change as needed)
files = Dir['*/*.mp3']
files.each do |f|
  Mp3Info.open(f) do |mi|
    mi.tag.artist = "Capitalization of the Band"
  end
end
