Sure, Tauren Wells’ rendition of *NSYNC’s “Merry Christmas, Happy Holidays” sounds great today, but it probably changed the trajectory of some people’s entire day when he sang it to weary Barnes & Noble customers when he worked at the store as a kid. “Before I was making music professionally, my favorite time of year was during the holiday season,” Wells says. “The lines get really, really long, so to entertain everyone, I would stand at the checkout and sing this song.” Now, you don’t even have to buy any books to hear it.
