In so many ways, the Christmas mash-up just makes sense. The holidays are a time of pop-culture overload, the airwaves choked with old chestnuts and re-recordings alike, with everyone from Bing to Beyoncé singing about Frosty and Baby Jesus. Between shopping lists and eggnog hangovers, how’s a stressed-out Scrooge supposed to digest them all? Throw ’em in the blender two, three, four at a time.

Bob Cronin, a/k/a dj BC, has done just that with Santastic! Holiday Boots 4 Your Stockings, a free batch of bastard-pop goodies tailor-made for the season. The Somerville DJ who introduced you to The Beastles is no stranger to making primo mash-ups of his own, but this time, he hit up some of his friends for help. "In early November, I PMed and e-mailed various bootleggers who I’ve encountered on GYBO.org, (Get Your Bootleg On), asking them to create a Christmas bootleg remix or mash-up," he writes in an e-mail. "Folks came through in spades with some great tracks."

And how. "Christmas In Boston," a track from legendary UK bootlegger Mark Vidler, a/k/a Go Home Productions, is not only regionally apropos, but really freaking good, weaving the Beatles, Boston’s "More Than a Feeling," and more into a surging sing-along. DJ John’s "The Christmas Massacre of Charlie Brown" peppers the Vince Guaraldi Trio’s "Linus and Lucy" with scratches and booming Led-Zep breakbeats. (Good grief!) "Turbo Sleigh Ride" and "The Nutbreaker" are dj BC’s postmodern twists on instrumental classics.

Others are pretty jaw-dropping. Cheekyboy’s "Biggie’s Last Christmas" tugs at the heartstrings by letting the late Notorious BIG do some Christmas rapping over "Last Christmas" by Wham! On "Fett’s Festive Fest," Fettdog parties with C-3PO, Homer Simpson, and Cake. On "Xmas Lists (The True Meaning of Xmas)," King Of Pants seamlessly melds Destiny’s Child’s "8 Days of Christmas" with the Jackson Five’s "Up on the Housetop" — and the Chipmunks. (And why not? Dave Seville’s vermin voice modulations were a precursor to mash-up technology, after all.) "Santa’s Acid Hawaiian Space Disco," by Mr. Fab and The RIAA, is pretty much exactly what it says it is.

And what about Chanukah? dj BC has it covered. His "Challahback Girl" — in Orthodox Mix and Reform Mix — mashes Gwen Stefani’s "Hollaback Girl" with "Hava Nagila" to find the Harajuku girl dancing the hora ’round the menorah.
