This year marks the 30th anniversary of Carey’s Merry Christmas album, which she’ll be celebrating on her “Christmas Time” U.S. tour starting November 6. Last holiday season, “All I Want for Christmas Is You” topped the Billboard “Hot 100” for the fifth year in a row, leaving any would-be pop princess usurpers trembling in her wake. The message is clear: Carey wants us all to bow down to her Merry Majesty — or else.
