If you're a certain age, chances are, that upon viewing the music video for "Fa La La" you will feel very conflicted. You might begin with a cynical ear. You might think Justin Bieber and Boyz II Men are an odd pairing, since he's just recently hit puberty and you were listening to them when you were pubescent. You might immediately decide that you hate it, thinking to yourself, Go back to singing "Baby," Bieber. I could really go for some "Motownphilly" or "Water Runs Dry" right now! And then, as the song goes on, you just might experience a bizarre out-of-body experience in which you see yourself head-nodding along to the music and even (gasp!) smiling. But probably, by the end of it, you'll just sigh and declare yourself "an old," like I did. Ah, well, at least Justin Bieber didn't desecrate Mariah Carey's holiday classic "All I Want For Christmas Is You," right? Oh wait.
