5. Elvis Presley, 'Elvis' Christmas Album'
Listen to Presley's "White Christmas" today, and you'll hear a reverent version with a touch of R&B, made effective by his powerful, emotionally direct singing. In 1957, however, composer Irving Berlin was so angered by it, he had his staff call radio stations around the country to try to get it pulled. This record didn't just pioneer the idea of rock versions of Christmas classics, it deservedly became the bestselling holiday album of all time.
