That was uncalled for, Nickelback. What happens if Paul McCartney sees your tweet and decides to look up your music and give it a listen? Beatle birthday ruined, that's what. Beatle suddenly considering suicide to avoid ever being tricked into letting such gunk enter his ears again, that's what else. Of course, maybe he'll be cheered up to finally hear something worse than "Wonderful Christmastime."
