2007: #7 - "LoveStoned"

People tend to rave about the shimmery interlude part (oooh look gtrz omg), and it's cool and all, but we love "LoveStoned" more for its dance-funk first half, where Justin out-sexies "Sexyback" and rocks "Rock Your Body" right to the ground.

And though "Rock Your Body" had far superior melodic hooks, it's on "LoveStoned" where Justin takes the funk groove of the earlier hit and outdoes himself on the Prince tip, going from flirty young dance goof to mysterious lothario with one falsetto swoop.
