Public Affairs Bring Sexy Back

New Music Alert: A pop prince and princess release their brand new singles, both with a dance vibe, and Energy begins spinning them this week. First up is Jessica Simpson, whose "Public Affair" sounds like it could have been lifted straight from Madonna's 1983 debut album (sing "Holiday" over the beginning chords, and you'll see what I mean). And Justin Timberlake returns after a few years' absence with "SexyBack," his take on combining a sparse, minimalist dance beat with an r&b groove.
