Lmao. It's also funny cause that is the exact song that came to mind when I saw "Iron Maiden" in the topic title (It was playing in mah head). <3 2 Minutes To Midnight.
*Edit* Maybe Justin Beiber is going to collaborate with Iron Maiden and sing on one of their tracks.
Well, ironically, before seeing this, I read in the newspapers that the band Bad Religion paid hommage to Celine Dion and Justin Bieber during the show, although I am not sure if it was in a positive or negative way.
After reading that, I started imagining Metallica going on a world tour with Justin Bieber >.<
