You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: track_replacer.rb
    path of file: ./repos/phishin/app/services/show_importer
    
    the code of the file until where you have to start completion: require 'highline'

class ShowImporter::TrackReplacer
  attr_reader :date, :track_hash

  def initialize(date)
    @date = date

    
  def scrub_filename(filename)
    return '555' if /555/i.match?(filename)
    return "Mike's Song" if /mike/i.match?(filename)
    return 'Free Bird' if /Freebird.mp3/.match?(filename)
    filename
      .gsub('.mp3', '')
      .gsub(/\AII?/, '')
      .tr('_', ' ')
      .gsub(/\d/, '')
      .strip
  end
