2. Britney Spears “I’m a Slave 4 U”

This is the one Britney song that came out that made me think Britney was really going to take it to that next level from teenybopper artist to full-fledged grown-up artist.  I don’t think it ever happened.  Maybe she should have had The Neptunes produce the whole album at that time.  Regardless, this is one sexy song with one sexy video.  It deserves the Number 2 spot.
