I’m a bit confused; if this is about debuts on the HOT 100, Why include All I Want For Christmas Is You? That’s not a debut. That’s not the first appearance of “AIWFCIY” on the charts. It’s a Christmas song that appears on the charts during the Christmas season, and continues to dominate the charts during the Christmas seasons. It’s irrelevant to include Mariah on this list and compare it to a debut duh of course it will fall off after Christmas. Heartless, Stuck wit u and Trolls are debuts!!
