Well, this one really applies to the past two weeks. It can probably also include the past 6 years if we’re really getting technical and the rest of our lives if we’re being honest with ourselves. Do you remember the first time you heard “SexyBack”? Yeah, me too. What about the first time you watched the video for “My Love”? Oh my god. You guessed it. The first Obsession of the Week (and our entire lives) belongs to Justin Timberlake and more specifically FutureSex/LoveSounds.
