25. Weezer, 'A Weezer Christmas' (2008)
If there's one thing the centuries-old tradition of holiday music has always lacked, it's irony. Weezer bring it by the sleigh-load on this six-song EP. Hilariously, they choose only the most Jesus-y tunes to bash out in their vaunted flat-lined power-pop style. When Rivers Cuomo sings "Oh, come let us adore him" on "O Come All Ye Faithful," his creepily deadpan vocals sound like he's stalking the Baby Jesus, not celebrating him, and on the pooch-metal rendition of "We Wish You a Merry Christmas," he's like a Dickensian droogy ready to burn his crummy Victorian orphanage if he doesn't get some figgy pudding, stat!
