I've been a Madonna fan since I was 7. I can't wait to hear her new song "Celebrate". I wonder what songs are going to be included to the Greatest Hits. I flew to London to see Madonna in London last July. I really enjoyed when she paid tribute to Michael Jackson. I'm also glad that she performed "Dress you Up". I really hope they release all her past tours on DVD/Blu Ray. I'm still waiting for The Re-Invention Tour" to be released. So please release it. PLEASE!!!
