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!!!
