The most popular Christmas songs on the radio? This cool infographic — citing data from ASCAP — says Rocking Around the Christmas Tree, Jingle Bell Rock and Blue Christmas were tops from 2000-2009. But hey, where is Santa Baby by Eartha Kitt…. and how about Bruce Springsteen doing Santa Claus is Comin’ to Town, which I’m thinking is ’90s? Also, I don’t think it’s a “Massive Project to Carefully Recreate the Christmases of Baby Boomers’ Childhoods” — I think we just like playing music… we like Christmas… and the best Christmas songs came from this era! Thanks to xkcd.com for this rockin’ graphic.
