And a beer!
Question: 10 to 20 years from now, do you think Christmas songs recorded by artists who are popular today (Destiny's Child, Christina Agulaira, etc...) will be heavily played like Andy Williams and Bing Crosby?
I don't think so. Granted, there may be one or two now popular songs that are still played but I believe the majority will be forgotten. The classics are that: classic. They will be here long after we're gone.
Just my two cents.
