Justin Bieber took the time to sign copies of his new album “My Worlds: The Collection” at the El Corte Ingles store in Madrid, Spain on November 29, 2010. The album is awesome because it includes all of the songs from his first two CD’s “My World” and “My World 2.0″ plus it includes all of the tracks off his latest album “My Worlds Acoustic.” Have you heard all of Justin’s songs, or are you still missing some of the albums?
