コメント一覧から、自分のコメントした記事に戻りたい

この記事を参考に、「5. 各ユーザーごとの投稿したブログ記事一覧が見れる」をやってみたのですが、

各ユーザーのコメント一覧から、そのユーザーがコメントした記事に戻りたいのですが、ルーティングの指定方法がわからず困っています。

『あるユーザーが投稿した記事に対してコメントした、その自分のコメント一覧を取得し、そこから、元のコメントした記事に飛ぶ』という感じです。
(この場合は記事ではなく、songに対してコメント、という風になっている）

おわかりであれば、回答よろしくお願いします。

index.html.erb↓

<% if @user.present? %>
  <h1><%= @user.name %>さんの記事一覧</h1>
<% else %>
  <h1>全ユーザーの投稿一覧</h1>
<% end %>

<% @comments.each do |comment| %>
  <li>タイトル: <%= link_to comment.body, ＃ここが何にしたらいいのかわかりません＃ %></li>
<% end %>

routes.rb↓

resources :comments

  devise_for :users
  resources :users, :only => [:index, :show] do
    resources :comments
  end

  resources :songs do
      member do
          put "like", to:    "songs#upvote"
      end
  resources :comments do
      member do
            put "good", to:  "comments#upvote"
      end
    end
  end

  root to: "songs#index"
