I never cared for ABBA until a couple years ago when a copy editor who made all my writing much better–and became a close friend–turned me on to their music. I'm still no diehard. And I passed on Mamma Mia! But I do have a bunch of their songs on my iTunes these days and enjoy quite a few. Actually, I always loved “Dancing Queen.” It just took me a long time to admit. Here's the video for Swedish pop sensation's charmingly sentimental single “Happy New Year,” culled from the band's 1980 album Super Trouper.
